mAllowEdit has really signified whether or not llpanelgroup was in its own standalone floater
This change removes the restrictions the lindens chose to put on group search, allowing the user as much control as possible over a group from outside a dedicated floater
Notices and Land & Money get their information from messages passed through viewermessage, addressed to the right instance by id, as such they must be unique to the standalone floater
Cancel button in group search will only enable when changes have been made and will refresh the group, clearing changes.
The OK button is not visible in group search as it serves the same purpose as the Apply button here.
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
