Added getObjects(...) method to edData to get objects whose keys match a pattern, for use with exits? cmd_dig(...) now adds the new room to the database (which handles the dbref getting) Fixed up adding Exit(s) to a Room in the room editor as well as saving them. Some potential new problems introduced (existing exits on/in existing rooms not loaded into Room Editor). Refactored cmd_roomedit(...)  and how it determines what room to edit. Added some methods (maybe not needed?) to ObjectDB. Added locking to NullObjects for use when I ignore a line in the database and substitute a NullObject. ObjectLoader modified to lock NullObjects generated when an ignore line is checked. New method addUnused(...) in ObjectDB made to check for locked NullObject(s) when seeing if I can add an id to the unused pile.
