- New A_Chase flags. 

- CHF_NORANDOMTURN: Actor will not randomly turn during chasing to pursue its target. It will only turn if it cannot keep moving forward.
- CHF_DONTANGLE: Actor does not adjust its angle to match the movement direction.
- CHF_NOPOSTATTACKTURN: Actor will not make its first turn after exiting its attacks.
