Make all datetime objects fully timezone aware

This is most of the transition to Django 1.4 `USE_TZ = True`. We need to
ensure we don't mix aware and non-aware datetime objects when dealing
with datetimes in the code. Add a utc_now() helper method that we can
use most places, and ensure there is always a timezone attached when
necessary.
