- some more checking and refactoring of ZatPoint calls.

- removed Plane/Floor/CeilingAtPoint functions because they are overkill for the problem they were meant to solve. Calling ZatPoint with adjusted coordinates created with AActor::PosRelative is just as easy in the few places where this is needed.
- made P_HitWater and P_CheckSplash portal aware.
