    Added additional logic to Walk-To cursor, if an invalid square is selected

    If you click empty space with the Walk-To cursor, it now looks for valid ground below, so you can walk down stairs and to lower levels, though you still cannot walk up this way.

    Added additional logic to Walk-To cursor, if an invalid square is selected, not a floor or is an empty space, it will check for a valid square below up to the Z level limit.
