GroupTags

GroupTags adds everyone's raid group number next to their player name in raid chat. So instead of seeing
[Raid] [Bob]: Hi guys.
You can now see
[Raid] [Bob]: [G4] Hi guys.

Options:
/gtags enabled (toggle mod on/off)
/gtags color (default, highlights the group number, e.g. "G4")
/gtags refresh (automatically done every 30 seconds to pick up roster changes)
/gtags whispers (off by default, also apply the [Gn] tag to incoming whispers)

Known bugs:
None
