* Remove a couple of functions from the group libs that are only used in one or two places:
 - get_owned_groups was only used on user/view and for the sideblock showing the groups you owned. We're going to show more than that now, meaning the function is wasted indirection for the one remaining place it would be used.
 - get_tutor_groups was only used on user/view, and has been broken by the group schema changes.
* Fix adding users to controlled communities. Still have to provide the ability to do this by dropdown.
* Fixed a bug caused by my misunderstanding of how (array) false works - it seems to make an array with 'false' as one value.

Prevent a crash when a group has no forum posts in it. Fix up some language strings on the group info page too.

Even though the code to implement getting strings from that place is not implemented yet :)

Removed get_associated_groups, moved its queries to the user view page and fixed its queries for the new schema.

This function is not used anywhere else, so it's safe to remove.

These types of error will most like occur in smarty templates.

Not porting to master or 1.0_STABLE just yet. It might need to have different behaviour yet.

Give the group ID element an ID so the js can access it. Remove the pretend form button for updating user membership.

Fix searching for users in certain groups, and the userlist element, given the group owner -> admins change.

The member list is able to be ajax-ly paginated through, and shows more detail than the previous one.

The page layout is showing shadows of what it will eventually become, although a lot of functionality isn't there yet - like joining/leaving the group.
