Group Bans!

Thankies Baker Linden~

Ported Ansariel's mAvatarNameCacheConnection change to mAvatarNameCacheConnections to llpanelgroupbulkimpl.h

Adds setGroupID in places, in case we ever want to add that.. but for now we don't really need/use it
Adds Refresh_Off icon from upstream.

Viewer Interesting changes:
Moves LLGroupChange out of stdenums.h into llgroupmgr.h
Moves roles_constants.h from llcommon into newview

This looks like it's better without space changes...
