Subject: [PATCH] Add badge quantity and rarity to /badges. (#238)
Implements feature request to know how many of each badge exists and
to have a 'rarity', a la Steam or PSN badges, relative to number of
non-lurker users.
Because Postgres `COUNT()`s are notoriously costly, /badges has been
memoized for 1hr to avoid a DOS target.
