Patch from Jonas Koelker to improve Filling's error highlighting: as well as marking a region as wrong if it has too many squares for the number written in it, this patch now causes a region to be marked wrong if it has too few squares _and no liberties_, so that it can't just be one the user is intending to enlarge later.
