i18n/L10n updates.
Superfluous whitespace removed.
Add FIXME in files with missing documentation.

Split up some list/form classes, and get the 'approve' and 'cancel' links on group member queue working.

Logic to have group joins turn into pending joins automatically when group is set to mod; allow users to cancel their pending group requests.

Replace explicit FormXHR setup for a bunch of simple AJAX form submissions with adding the 'ajax' class on them.
This avoids having to add extra custom JS bits just to initialize forms using the common AJAX submission path.

- fix <activity:subject> generation so we get the profile info (what's available so far)
- use id instead of nickname for group join/leave forms so we can join/leave remote groups
  while the rest of the groups UI remains limited to local groups
  (plugins are responsible for making sure remote notifications and permission checks are done)
- fix remote notification when joining group through OStatus's remote subscribe form

This is the first pass at a group home page.
