[gnome-2048] Improve a bit responsiveness.

[Arnaud B. <arnaudb src gnome org>]

commit 32ce636b4eb2f883c1eb27eb1c3315fd4438c6ee

    Improve a bit responsiveness.
    
    Not sure why, but each move finished
    by a 100ms timeout that was blocking
    game. Just delay that way the finish
    dialog, and allow an immediate play.
