Make the "Buy a Ticket" button font consistent across platforms.

The "Buy a Ticket" button currently uses a font stack based on Rockwell. It
is a lovely font, but it's not available everywhere. The button looks quite
different on Android, desktop Linux, and anecdotally on Macs. I'm sure it
looks different on Windows too.

This pull request changes the font stack to fall back to Rokkitt, from the
Google Web Fonts collection. As best I can tell, it's quite a close subsitute
for Rockwell.

Closes #45
Enhance the Venue page copy regarding public transit and parking.

Adding some more details on subway stations and also parking information.

It's worth noting that I did *not* run "make i18n". Doing so introduced a
whole slew of changes apparently unrelated to mine, so I didn't want to
clutter everything up and also possibly introduce unexpected side-effects.

Relates to #29, but doesn't quite close it.
Adding hotel price info.

This will also need a "make i18n" -- and of course, a fact-check.

Closes #63.
Adds attribution and license information to Code of Conduct page.

After a "make i18n", this closes #41.
Adds information on meals and food in the area.

See #30 for reference. The test used is that suggested by @wolever.

This will also require a "make i18n".
