    Mosaic: make solver notice when it gets stuck.
    
    The top-level solver loop had a boolean 'made_progress' among its loop
    conditions, on the theory that if the solver got stuck then it would
    fail to make progress and the loop would terminate after it had tried
    everything it knew how to do. But made_progress started off as true,
    and nothing ever set it to false, so this check never did anything!
    
    Now we set made_progress to false at the start of each iteration of
    the outermost while loop, and then if we scour the whole grid without
    setting it to true, the while loop will stop and solve_game_actual()
    will report failure.
