Added else if(..) case for ExitType.DOOR in loadExits(...) from ObjectDB, not sure if adding door type exits to both rooms is a good idea. Renamed setDest(...) and getDest(...) methods of Exit to setDestination(...) and getDestination(...) respectively. Added override indicator to similar methods in Portal, a subclass of Exit, since it had those names first and needed to avoid method name clash. Added origin field to Exit for the Door exit type. Added ThingType enum to handle Chest(s). Updated toDB() method in Chest. Cleaned up some spacing in: Item, Thing, Chest. Small changes in MUDServer due to method name refactoring above.
