There were a few things the W3C validator complained about that I
didn't bother fixing (like img tags without alt attributes and
obsolete tags). There also a few pages that were slightly more
annoying to get my local instance to render (like the 404 and 500
error pages), so I checked those by eye.
This does not cover the actual app at all.

Checked using the following (relevant for rebasing):
git grep url templates/ | grep -v "'django" | grep -v "'zephyr"
This appears to not have a good backwards-compatability story (well,
there is one involving a %load from the future, but it seems to not
work).
