Removing lists from MUDServer and putting into ObjectDB.

MUDServer is terribly long for a single class. :(  This should organize
things better.
using the actual enum for game mode, moving player collection to objectDB
added TimeOfDay enum, put TimeLoop into own file
removed message loop

There's currently no reason to queue up the messages instead of just
sending them immediately.  Synchronizing access to a collection/list
does not prevent ConcurrentModification exceptions!
Removed RoomType map and replaced with use of existing roomType enum
made flags enum
