- refactored P_FindFloorCeiling to be portal aware and cleaned up its interface.

A big problem with this function was that some flags required setting up some variables before calling it and others did not. It will now set everything up itself so all initializations to AActor::floorz and ceilingz that were made before these calls (which were all identical to begin with) could be removed and the internal initialization logic streamlined.
