[Michael Catanzaro <mcatanzaro src gnome org>]

commit dfb23c124eb9c6c6e5f724e6a8dc97cb0994f793
Author: Michael Catanzaro <mcatanzaro gnome org>

    Remove the Claim Draw menu item
    
    Instead, we should prompt the player when he has the option of claiming
    a draw. This will come in the next commit.
