Subject: [PATCH] add the ability to Exile cards face down.  Added an
 ExileFaceDown$ True parameter to ChangeZone and ChangeZoneAll.  In the GUI
 code, I had to change the ZoneAction (for viewing Exile, Graveyard, etc.)
 class to not use the YieldUtils iterator stuff.  I pull the Generator into an
 ArrayList.  If someone can do it with Iterator, go for it.
