- Used new functionality to avoid moving the puff around in SpawnDeepSplash.

Browse source 
- Fixed: P_RailAttack used the shooting actor or a default puff for some splash
  related actions. It should use the puff type passed to it as a parameter instead.
- Changed splash handling in P_LineAttack to use the actual hit position to
  spawn the splash and not the puff's spawn position which is offset a little.
- made some precision related changes to P_HitWater. The precise hit coordinate
  can now be passed as parameters.
