Blog: typo fix in template.

Template had a typo from last commit.

Blog: add permalink on partial entries.

I noticed there is no link on the blog pages (other than on the front
page) to get the link to the blog post itself. This adds a permalink at
the end near the tags.

I considered making the title itself a link, which is what's done on the
frontpage, but I figured this might look nicer. Feel free to change
this if you're looking this commit message and feel I didn't DTRT
here. :)

admin: Fix query parameter manipulation in showAddAnotherPopup.

This should fix the bug in, i.e., adding tags from the blog entry admin
page.

base: Start progressbar for new match.

This code should be easier to adapt to future matches too, by just changing
the constants in the first `with` declaration and whatever text is desired.

blog: Remove unnecessary kwargs manipulation from custom_index.

I don't know if this code is left over from previous versions or what, but
it's not doing anything now. custom_index doesn't pass kwargs to anything
else, so there's no need to fiddle with the dict so much.

supporter: Remove bogus value for PayPal srt variable.

srt is meant to be used for time-limited subscriptions. 0 is not a valid
value. See
<https://developer.paypal.com/docs/classic/paypal-payments-standard/integration-guide/Appx_websitestandard_htmlvariables/#recurring-payment-variables>;.
It's optional, and leaving it unset gives us the behavior we want, so do
that instead.

supporter: Set LC for all PayPal forms.

This setting is not subscription-specific, so if we ever do it it seems like
we should always do it.

css: Implement #sidebar and #mainContent without floats.

170aa38bb5c3972293846aa4d86540b4967effab fixed one bug but added another:
#mainContent would always be the max-width of 1000px. If the user's window
wasn't wide enough to accommodate that alongside the sidebar, it would be
rendered below the sidebar.

Fix that by using positioning instead of floats, so #mainContent can have a
flexible width.

FY 2015 Form 990, CHAR500, & auditors' report.

Our Form 990 Filing deadline was today, 2017-01-17. As is our usual
practice, we make them publicly available on or before our filing
deadline date.

This commit includes our USA IRS Form 990, NYS CHAR500 and the
independent auditor's report for FY 2015.

supporter: Reorganize form post-input notes.

This makes it easier to keep baseline alignment between labels and their
respective inputs. Declaring `margin-left: 51%;` for the post-input notes
is not exactly what we want, but it's much closer and less troublesome than
dealing with the vertical alignment of labels otherwise.

supporter: Refactor amount-checking JavaScript.

* Separate out amount-parsing and reacting into separate events. This sets
the stage for other elements to react to the custom
'conservancy:newamount' event.
* Set up events in the context of each supporter form, with closures. This
lets us avoid weird CSS selector gymnastics in the event, and instead
drill down from the form to find the elements we need.

There are no functional changes in this code, barring bugs.

sponsors: Unlist too-old sponsors.

These companies have not given in the past year.

supporter: Women's shirts, not ladies' shirts.

Signed off by Karen.

supporter: Improve amount validation JavaScript.

* Check validity on page load and store it in a data attribute so we can
change validity state more accurately.
* Clear invalid state on any change.

supporter: Improve shirt selection JavaScript.

* Add an animation for state changes.
* Set the start state by triggering the event on the selection at page load.
Firefox at least remembers the selected button on page load. This avoids
a situation where the user says they want a shirt, reload, and now the
size selection is invisible because we used to hide that unconditionally.

supporter: New form styling.

This makes better use of bigger screens, and degrades better to smaller
ones.

supporter: Move more presentation rules to CSS.

This commit keeps the presentation basically the same, it just moves
presentation rules out of HTML and into CSS. It's not pixel-perfect but
pretty close.

supporter: Only render the Annual form for upgraders.

This lets us do more with HTML and less with JavaScript, which is always
nice.

supporter: Make a partial for the supporter form.

This commit shouldn't make any substantial changes to the form or its
presentation. This is just cleaning things up as a development aid.

js: Render <video> inner HTML when no source is supported.

The HTML inside <video> is meant to be rendered by browsers that don't
support the tag at all. You have to respond to the JavaScript error event
to deal with browsers that support video, but no available source. See
<https://developer.mozilla.org/en-US/docs/Web/Guide/HTML/Using_HTML5_audio_and_video#Showing_fallback_content_when_no_source_could_be_decoded>;.

css: <dl>s clear each other.

This prevents <dl>s from stacking horizontally when their <dt>s are short.

css: Remove unused rules.

The rationale given in the comments for these rules no longer applies: there
are no divs with class column or conservancy-blog on any pages. Meanwhile,
they're causing unwanted styling: we started using the column class on the
front page for two-column layout, and the videos are appearing smaller than
desired there. Just remove these.

news: Refactor press release rendering into a partial.

Same rationale as a few commits ago for blog entries.

news: Render HTML entities in press release titles.

Same rationale as for blogs a few commits ago.

blog: Headlines clear floats.

This avoids a situation where multiple summaries have floats that stack on
top of each other vertically, which end up getting far away from the actual
text.

In order to make this work, we had to change the styling of #mainContent on
blog pages (and others with a sidebar). Otherwise, headlines with
class="clear" would clear the sidebar as well.

blog: Refactor entry rendering into a partial.

This helps ensure that entries are rendered consistently wherever they
appear.

blog: Mark entry headline safe in title.

We already strip tags, but this lets HTML entities render correctly.

css: Remove noop rule.

This wasn't doing anything because "line-height" was misspelled.

supporter: Add id="renew" to the renewal form.

This provides better behavior for non-JavaScript visitors who use a #renew
link (see last commit).

js: Rewrite #renew links to the Supporter page.

#renewal is the correct hash to use.
