Improved handling of static/build and css generation

When the container is mounted, the local contents of . obscure
/app/symposion_app in the image.

Generally speaking, this is handy for development, as it means that
local changes are detected and used immediately without needing to
restart the container.

However, it breaks in the specific case of the sass->css
generation. Prior to this change, the css is generated only after the
first time a page is hit. The generated file is placed in
static/build; however, due to the obscuration, this generated file
isn't visible to the running process.

The next time the container is built, the pre-existing static/build
directory is copied into the container as it's being built; then,
later, that version is what gets served.

This change adds the needed libraries to pre-generate the css as part
of the image build, and runs compilescss to do this, prior to the
collectstatic step.

It also adds a second collectstatic into the make_dev_container
script, so that the visible static/build directory should ahve the
same contents as the obscured static/build directory. It also expands
the .dockerignore file to make sure these files aren't copied into the
image in future.

I'm not sure if this is the right thing to do, as changes to this
directory will be ignored, which could be confusing. Perhaps never
being able to see these generated files is better?

Conflicts:
pinaxcon/templates/symposion/schedule/_grid.html

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.

dj-gapc-storage fix for num_retries went upstream

Fix for an attribute error in this module has been merged upstream and
been released as 0.4.1

https://github.com/eldarion/django-gapc-storage/pull/17

require django-bootstrap-forms

While pinax-theme-bootstrap pulls this in, we use this directly too, so
we need to put this into our top level reqs too.

Remove metron

Not used - old/depricated name

Update requirements for Django 1.11

This has long enough support to reach post conf + a fair bit.

Support Django 1.10

Few minor changes to support Django 1.10

Store user files in GCS - Ephemeral Disks

Issue #2

Bind in djangosaml2

Our authn is provided via shibboleth

Remove wagtail

This should eradicate wagtail from the project.

While wagtail may be nice, our goals are to keep all things public, and
having things locked behidn a DB is congruent to that plan.

All in all, the django project only leveraged a single wagtail feature,
"richtext" which has been hacikly removed and will result in bad display
of however it comes up. But this is on homepage.html, which will be
removed and covered up with a static website, which means we should be
able remove homepage entirely from this project.

This reduction hopefully makes the monolith easier to understand,
maintain, and wield.

Remove dj-user-accounts

That's a nice macro, but we don't need it.
dj-user-accounts stands in the way of using more generic AUTN_METHODS

Remove boxes

Boxes takes content directly from the DB and drops it into the django
templates. This is rather ugly and goes against keeping as much as we
can in static locations. As such, this is being dropped.

Drop the wiki

Whatever wiki is used, will be run as a standalone application that is
not part of the primary application.

Closes #4

Revert "Switched to using posgresql for db."

Add MySQL deps

Default content page and sponsor list is working, mostly.
TODO: get sponsor logos to show up instead of the names (text).
