Filings: audit deadline extension was granted a while ago.

Update text to indicate we have that extended deadline.

static.views: Deduplicate code.

The primary goal here is to get templates rendered more like our "regular"
templates, by using more of the standard tools to do so rather than roll our
own.

* Use TemplateResponse. This requires less boilerplate and ensures the
rendering runs through our local context processors.
* Use the existing definition of fundgoal_lookup.

templates: Finer-grained split of fundraiser header display.

Always show the header if a fundraising goal is active.
Only show the progressbar if there's money in it.

manage.py: New file.

To bring the project in line with modern Django apps.

HPE no longer a sponsor of Software Freedom Conservancy.

HPE sponsorship expired and they did not renew.

wsgicustom: Import _strptime to avoid race conditions later.

See the linked bug for details.

robots.txt: Revert change from last commit.

Not relevant.

robots.txt: Disallow from /supporter.

This is a hopefully temporary change to help mitigate the recent activity
we've been seeing.

Blogs/news only include a single OG image/video.

For now, this gives us more assurance that other sites will choose the
preview we want.

You can control the selection by adding data-ogpreview to image, video, and
source elements. data-ogpreview=0 excludes the element from being included
in the preview. Positive numbers set the preview priority. The lowest
value found is chosen first.
