RoomData now has monsterMgr and waypointMgr members, so that it can
compare it's characters to the monster & waypoints, etc.
RoomManager has been updated. It now has a database reference, which is
passed to the monsterMgr of new rooms. The room API also has functions
which expose these managers to lua.
I actually don't remember what the RoomData's lua references where for,
but I'm pretty srue it wasn't this. I'll figure something out when I've
had a sleep.
I've changed some naming concentions in the lua APIs. I've also made a few
other tweaks, like region_pager_api.cpp delegating to the passed
RegionPager object. This won't explicitly run, becuase there's still a few
more changes needed.
