- added information about the role of the aa site
- moved handling of ground name from tgo to the sam generator to make the tgo cleaner
- adjusted the skynet-config lua to the changes
The changes for Skynet unfortunately broke this because the names used
by the TGO and the name of the group itself were no longer in sync.
This deserves a larger cleanup where we decouple that naming
requirement (TGOs don't need a lot of the data they currently have),
but this works until we have the time to do that.
