Add admin action to update slot names

* The slot object updates its name every time it is saved
* But sometimes its slotrooms are changed underneath it, and so the
name can become out of date
* This method is a simple way of updating the names for all the slots

Chrisjrn/session chair (#94)

* Adds session_detail page

Conflict and migration performed by Sachi King <nakato@nakato.io>
Emoji changed, lca2017_tags to lca2018_tags, remove needless dependency
on django-user-account, use request instead like the remainder of the
calls n the template do anyways.

Remove blocktrans from a number of texts as they break {{ templating }}
and we don't translate anyways.

Add support for a "ready for boarding" group

This allows for the boarding functionality to be safely tested with
just a subset of users first. Once you're ready to go live Fur Reals,
just delete the group and all users will become eligible.

Create regidesk app

Shows summary of all attendees with a paid ticket, including
boarding_pass status.

Currently, regidesk allows staff with the requisite permission the
ability to view the checkin status of attendees, and email the user
their boarding pass email.

Included is a view for the user to retrieve their own QR code (in case
they got the plain-text version of the email, they can use this to
download an image to their phone for faster checkin)

More consistent color-coding for talk status buttons

- there's no btn-default, switch that to btn-primary
- consistently use info for standby, primary for undecided, success
for accept and warn for rejected

urlize abstracts

I've looked through the database and I can't find any accepted
proposals that actually contain anything to linkify - but I've had
several requests from people that I think are reasonable, things like
being able to link to their project (we ask them to provide a project
url but we don't use that link)

This seems like a reasonably fast way to let those people add a
link. We still have to manually accept changes to their proposal so we
have a chance to look at the content of the url if we want.

The urlize filter adds rel=nofollow to the link automatically.

Modify limits report to include category inclusions as well

* A TimeOrStockLimit limit can apply a limit to a whole category, or
to specific products
* This report was only counting the products directly listed
* Take advantage of the new all_products property to include the
products indirectly listed as well as those directly listed

Add an all_products property to FlagBase

It's common to need to query the fill list of products covered by a
Flag - whether directly, or by being in an included category.

Add an all_products property which does this.

Add ticket_type property to Attendee

This vastly simplifies templates and many many things which need to
look this up.

Voucher form needs to be processed first

Because otherwise, the firstform (which will not be in a valid start)
throws errors which prevent the voucher form from ever being processed.

* Fix categories for badge icons, company names

* Company names had a misspelled filter and weren't being displayed
* Add some conditional logic so that company names don't get shown for
hobbyists or students

Make our fonts available to the system

To make them more useable by cairo

Add support for badge PDFs also

* Add a greyscale filter to text for more accurate preview
* Always default to SVG preview as it's the most accurate (cairo
doesn't do a great job of handling custom fonts when it converts to
png/pdf)
* Always use roboto font.

Further changes to support badge generation for lca2018

* Undo some of the debugging done early in this series of patches
* Add ability for a user to preview their own badge
* Add a template for the LCA2018 badge

Badges work by copy-pasting lca2017/pyconau2017 code around

WIP - Push for share

Revert "Fix off-by-one error in rowspan calcuations"

This reverts commit 96a24489b6d2a2b14d9bc2913cdb8183481ebfd1.

Order slots by room order first

* lca2018 has a situation where we have multiple slots starting at the
same time, but ending at different times
* The headers of the timetable grid are sorted by room sort order
* In sqlite at least, ordering by start,order seems to implicitly
resolve duplicate start times by looking at the other sort fields
first, and will only sort on order if all other fields are identical

* This results in the slot that ends first going in column 1, which
gets out of sync with the room listed in the header

* I can't figure out how to solve this in the database, so...

* Force the slots to be sorted by room order.
* Then, for each start_time, select out slots starting at that time
and operate on them
* This both gets the slots in the right order *and* keeps multi-room
slots with the right colspan. Yay!

* It's possible that this wouldn't be needed on some DBs which might
do the sorting differently.

Display Room for everything that's not break

Talks, tutorials, plenaries, miniconfs - everythign except breaks please.

List rooms in slot admin

In many parts of the schedule there are multiple slots with the same
start/end times, and it can be hard to find the one you want to edit.

Make this slightly simpler by listing the room names in the admin list.

Change "Apply voucher" button into a link

I can't find the form that should be displayed here, so the simplest
thing I can do at 11pm is to make this a link. That's unsatisfying but
hopefully works.

str values before bleach

Can't operate on objects, stringing seems fine here, there's a lot else
already randomly str() before bleach.

Disable client-side validation on credit_note forms

* HTML5 browsers have some clevers to do client-side validation of
forms
* Django activates this by default for certain field types
* However, in this case, there are three forms on this page. We rely
on two of them being invalid in order to figure out what processing
to do.
* So we need to disable the client-side validation.

Remove unicode warning

We now support more unicodes so remove the warning

Include templates in sdist

Adds a MANIFEST.in to ensure that templates are included in the built
package and thus available in systems that install this package.

Display Condition type in list views

* Whether a Flag is disable-if-false or enable-if-true is a very
important detail
* But one that's easy to get wrong
* And it's hard to spot problems without inspecting every single flag

This change adds the Condition into the various admin list views, so
that it's easier to scan them all for problems and look for inconsistencies.

Enhance proposal fields display

* Display the "withdrawn" status
* Display extra information about exhibitions for art+tech

Improved menu styling

Update menu to use same style as static site,
with slight adjustments for Bootstrap 3.

Update fonts

Use the same fonts as the static site, as per the LCA2018 branding guide.
Shrink headings on the Dashboard to suit new fonts.

Don't try to initialise dataTable twice

Old code was initialising the dataTable twice - once in the parent
block and once in the child. This doesn't actually work and just
caused errors.

Switch to only initializing it once. Unfortunately this creates
copy-pasta :(

Don't duplicate existing rooms when importing schedule CSV

* Old implementation needs to see exactly the same rooms in exactly
the same order every time it loads new data, otherwise it will
create a duplicate entry for the room that differs only in display
order.
* New implementation ignores the display order when checking to see
if the room already exists.

If there are no track names for today, don't show the row

If there are track names today, show the row for track names. If there aren't, don't show an empty row.

Only copy visible columns on attendee reports

Also, add the ability to choose which columns are visible.

Improve display of abstract and presenter bio

Relocate buttons to be beside the presenter's name.

Format abstract and bio in monospace hack as intended.

Restore buttons referenced in current templates

Partial revert of 271d9e05 - these are two of the many files removed then. Looks like these are the only two still used.

Improve mobile view of schedule

Don't show the table header in mobile view

Make talk audience and format visible to reviewers

* Audience is visible on review details, but not the list. Perhaps
useful for cases where reviwer wishes to only review for a
particular audience. This change adds audience to the list view.

* Format is not visible anywhere. This changes adds it to list and
detail views for the reviewers.

This change also adds some buttons to control visibility of the new
columns.

Supply a default value for target_audience for the ART+TECH miniconf

* The base model requires a value here
* But we aren't using one; so there's none on the form
* This change supplies a custom enumeration that's specific for this
particular model, which has one value, which is a default value,
which simply says that the field is N/A
* This does mean that when viewing or reviewing the proposal one sees
the Target Audience field, but it will say N/A.

* Testing has shown that this does not affect the other types which
descend from the base Proposal class; they still use the default
enumeration.

Require login for proposal submit

- This has the effect of bouncing people to the login page if they're
unauthenticated, rather than returning a 502 because 'home' doesn't
exist.

- If they're authenticated but don't have a speaker profile, send them
to the speaker profile create page rather than just to the
dashboard.

Increase uwsgi buffer size

The DataTables sets a lot of data into some cookies. It's currently
overwhelming the uwsgi buffer size.

Revert "Split out dev/prod docker builds into parallel jobs."

This reverts commit d7065ee43d31f55b1ad9860d3cb5e1cbdb747e73.

Dev build re-uses prod build, so they can't be split (and dev build
won't take much extra time anyway)

Utilise multi-stage docker build for consistent dev/prod base

* developers can use --target symposion_dev to get a responsive site
that reads from their homedir and reacts to changed files instantly
* without a specified target the default is to build the prod image,
which is identical except for running uwsgi instead of the django
built-in server
* Enable debug when running in a developer's test environment
* Remove the makemigrations script and dockerfile
