After discussion with Simon, the game redraw functions are now passed a new

argument `dir' which tells them whether this redraw is due to an undo, rather
than have them second-guess it from game state.
Note that none of the actual games yet take advantage of this; so it hasn't
been tested in anger (although it has been inspected by debugging).
