    Add a delay between the last move and final flip
    
    Currently, it often seems like the final player has placed a piece
    of his opponent's color instead of his own, since after clicking the
    piece that is shown placed on the board is the one that is fated to be
    there after the final flip. This is confusing and made me think I was
    seeing Bug #679137. Add a delay to prevent confusion.
