Merge branch 'testing' of gitorious.org:statusnet/mainline into testing

* 'testing' of gitorious.org:statusnet/mainline:
  OStatus: if no <link> available and no profileurl hint passed in, use object id if it's an HTTP(S) URL. Fixes profile link for Google accounts.
  Tweak common_url_to_nickname to take the last path component; fixes pulling nicks from Google profile pages (path is "/profile/<nickname>")
  Fix bug on subscribe/unsubscribe in profile lists. Bogus call to nonexisting profile->getProfile() was masked by DB_DataObject
