 Introduce caching for group memberships.

 The new system works like this: The `bp_groups_memberships_for_user` cache
 group stores arrays of membership IDs for individual users. The
 `bp_groups_memberships` cache group stores data about individual
 The new function `bp_get_user_groups()` populates a user's group
 from these caches, and filters them as requested in the function
 Then, the various `groups_is_user_*()` functions use
 instead of direct, uncached database queries to fetch their data.

 In addition, the `get_group_extras()` method of `BP_Groups_Group` can now
 greatly simplified, since all necessary pre-fetching of current-user group
 memberships happens via the `bp_get_user_groups()` cache.

 Props boonebgorges, dcavins.
