- more transition to FMultiBlock* iterators:

Browse source 
* removed all code for dealing with z-displacing portals in the iterator loops. This would cause too many problems so I decided to scrap any provisions for allowing interactive portals with z-displacement. They will remain restricted to pure teleporter portals.
 * changed spechit to carry a position along with the special line. If something is activated through an interactive portal this is needed to calculate movement.
 * pass the abovementioned position to CheckForPushSpecial.
 * collect touched portal lines in a second array analogous to spechit.
 * use FMultiBlockThingsIterator in P_TestMobjZ.
