Sezz

Imo a class will be most convenient and easy to use. Essentially this, but a Lua version: https://github.com/MontyTRC89/TombEngine/blob/sezz_point_collision_class/TombEngine/Game/collision/PointCollision.h

Planned for some time, but state refactors must first be completed to avoid reverting to Core's horrible buggy mess that produced the original clunky behaviour to begin with. ;)

Full adoption of new functions complete.
