Types 0A and 16: the outlaw who is wanted at this level. A bullet hit sets OutlawShotFlag to one, which makes FinishTownStage end the stage. Otherwise the outlaw wanders about the town: if he touches the sheriff, the sheriff dies. Type 16 is made by CreateOutlaw instead of type 0A when the outlaw is to be a little faster.
