- Changes to both A_MonsterRail() and A_CustomRailgun(): Save actor's pitch,
use a larger aiming range, and ignore non-targets in P_AimLineAttack().
use a larger aiming range, ignore non-targets in P_AimLineAttack(), and
aim at the target anyway even if P_AimLineAttack() decides it has no
chance of hitting.
- Added another parameter to P_AimLineAttack(): A target to be aimed at. If
this is non-NULL, then all actors between the shooter and the target will
be ignored.
