Added a version of the getThing(...) method that takes integers. Fixed saveDB() since the clone() method doesn't actually copy elements of the object. Added the methods getZCoord() and setZ(...) to the MUDObject class. Inserted a tad bit of code to set some object variables on a thing to the setup() method. Added a few trooms and a Thing to the db manually.
