Handles a tribesman (sprite IDs 38 to 3F). Bit 2 of the sprite ID is set when the tribesman is facing right.
A tribesman wanders about the room with the velocity chosen by ChooseTribesmanVelocity. If it touches the player then it hurts the player and is thrown away (see SetTribesmanVelocity). When a tribesman is close to an amulet piece which has not been collected (see TestAmuletProximity) it flashes yellow and plays a sound.
