new trigger features: triponce, tripcondition, and trippedby.

Browse source 
once fires off callbacks one time,
condition lets you plug in an a==b, or method that returns a true/false;
 trippedby lets us plug in things like $TypeMasks::PlayerObjectType ( ac39577543/Engine/source/T3D/gameFunctions.cpp (L658) ) so that *only* players can trigger it
