When something goes wrong with a move (typically because of undo), the move stack and server's idea of whose turn it is get out of sync. Since it being my turn means it's up to me to put the next move on the stack, let the stack own "next turn". (Can probably eventually get rid of the ServerCtxt variable that tracks it.)
