Subject: [PATCH] Grayout Machine Match menu when aborting match

Clicking the Machine Match menu item when a match or tourney is in
progress will make XBoard drop out of match mode when the game finishes.
The check mark will remain on the item until that moment. But now we
gray out the item to show that the match is scheduled for termination.
