LLGroupActions too! (Strengthens RLVa restrictions!)

Cleans up llfloatergroupinfo, makes it an instance tracker... pretty much as nice as llfloateravatarinfo now ^*^
Adds notifications JoinGroupNoCost and JoinedTooManyGroups (added to our existing translations, of course)
Cleans up all around, placing groupactions around.

Touches up bits for avataractions
