Removed MonsterManager's Singleton status, RoomData now has mgr members

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.
