Subject: Start of trying to make Region/Scene more modular. Added preliminary
 IRegionModule interface. Also have a work in progress way of Modules
 registering optional API methods (kind of like Apache optional functions).
 But there must be a cleaner/nicer way in c# of doing these than the current
 way. Added three work in progress modules: ChatModule (simple handles in
 world chat, but by moving this to a module, we could support other types of
 chat modules, ie like a irc - opensim bridge module. ) , AvatarProfilesModule
 and XferModule. Moved most of the code from  Scene.ModifyTerrain() into the
 BasicTerrain library, as the start of trying to make that more modular.
 Stopped Child agents showing up as part of the "show users" command.
