Recent minor changes (promotion, room sectors, teleporting)

1. We congratulate Graven on his promotion to Maia (Wright).

2. Lots of incorrect room sectors have been changed here and there around Arda,
   for example from BUILDING to CAVERN. The most visible consequence of this is
   that mappers tend to lose synchronization when you enter a modified area.

3. Some area/zone definitions have been modified around the Anduin and Mirkwood.
   This causes some changes to the game, mainly to teleporting in the eastern
   parts of Arda, as the locations from where to where one can teleport, are
   now slightly different than earlier.
