des.region() accepted booleans for the joined field, whereas des.room accepted xchars. These were only being used as truth values, so this converts the room ones into booleans for consistency. I don't think accidentally using an int or a boolean wrongly would actually crash the level generator, but consistency is good. This converts an schar field in struct mkroom into a boolean; on most systems these are probably 1-byte types and save files won't be broken, but it might be best to treat this as a save breaker anyway.
