Get Moving Tiles code out of collision.cpp/h

[qxdFox]

much needed refactor, will also help with getting roulette tile code to quads -> I want to move away from using tiles and just use quads for most of my stuff

move moving tiles code from collision to /foxnet/zones

Okay this isn't possible cause gamecore and collision is shared but it could still get a cleanup I believe
