Fixed bug where the StateEnumerator would create illegal states (ie. ignoring whether or not the opponent was able to pick up or pass or place a bone).  The AIPlayer works once again!  Going to remove debug messages now...
Tidied up some debug code, added example to ExampleCleverPlayer that shows off guessing what the opponent is about to do.  Also created a psvm to test my AI against a short-sighted AI (I win 80% of the time!)
