handles kgs-genmove_cleanup command
There is something else that still needs to be fixed here
fixed kgs-genmove_cleanup
added bestCleanupMove() to player that just calls bestMove().
besCleanupMove() is overridden in MctsPlayer to handle
kgs-genmove_cleanup().
Recovered .sgf files used in tests.
Merge branch 'master' into kgs-genmove_cleanup
