[gnome-chess] Display claim draw dialog unlimited times per game

    Display claim draw dialog unlimited times per game
    
    Let's adhere to the rules of chess, and give the player a chance to
    claim a draw whenever entitled to a draw.
    
    Disadvantage: in draw scenarios, this causes a pop-up dialog to appear
    on every turn.
