- Added JLOSF_NOAUTOAIM flag for when you want to use A_JumpIfTargetInLOS in conjunction with

something that never autoaims, such as a railgun.
- Fixed: A_JumpIfTargetInLOS should use P_AimLineAttack() instead of P_BulletSlope(), because the
  latter intentionally checks to the sides of the aimed line.
