Update timecop dependency to version 0.6.2.2
Match case sensitive first. Fixes #584
Update DB name to reflect case of spec
Don't use ILIKE, it does matching instead of straight comparison
Disallow name case changes when there are indexed versions

This makes the lookup case insensitive still, which protects against
multiple users having gems like RAILS or nokogirI. But it fixes an edge
case where the owner might want to change the gem case. We don't allow
changing it when there are indexed versions because doing so screws up
the index matching the filenames of the gems on disk.

profiles can link to gittip.  api changes for gittip integration.

Users can add a gittip username to their profile, which will cause
their profile page and the gem pages for any gems they own to link
to relevant pages on gittip.

As well, some API changes were needed so gittip could integrate
effectively.  These include:
  1) gems/:gem_name/owners.:format now includes the gittip_username
     when the relevant profile has opted in.
  2) profiles/:username.:format now exists, and returns profile info.
no more xml/yaml!
