    Singles: fix spelling in a validate_params error.
    
    'height', not 'neight'. Apparently has been misspelled since the
    puzzle was first committed. I suppose they look similar enough that it
    never caused a problem.

    Singles: prevent hangs at low puzzle sizes.
    
    A user reports that trying to generate a 2x2 or 3x3 puzzle at Tricky
    difficulty causes the generator to hang, for the usual reason that
    there aren't any - puzzles of that size are either ambiguous or Easy.
    
    The usual response in this code base is to quietly downgrade the
    puzzle difficulty when absolutely necessary, so here's some code to do
    that (and also for 2x3, which the user didn't test, but unsurprisingly
    behaves the same way).
