Added new functions as variables of polyobj_t:

Browse source 
* po.pointInside(po, x, y) as a wrapper for P_PointInsidePolyobj
* po.mobjTouching(po, mo) as a wrapper for P_MobjTouchingPolyobj
* po.mobjInside(po, mo) as a wrapper for P_MobjInsidePolyobj

I can confirm that ":" syntax works with all the above, e.g. po:mobjInside(mo)
