Shirts: Close order page

The deadline has passed for ordering shirts, so
disallow that from happening.
RSVP: Disable follow reservations

We need more leads to rsvp to have a fun event,
so turning off follow reservations for now. It
would be nice to build this feature into the
system in the future, but this works for now.
RSVP: Bump version of 1.html

Rename 1.html so that deployment refreshes.
Schedule: Add cover prices

At prices for the door if folks arrive the
day of the event.
RSVP: Change weekend pass to be $50

Price increase.
RSVP: Low housing indicator, remove shirt option

The event is near. We're out of housing options,
and the shirt order has already been made.
RSVP: Adjust follows sold out text

Make the text read a little better, and be
consistent with the Facebook event.
