So finaly went with Box2D

Integrated box2d into the project to decrease the work time required to implement my own collision/physics system.

So far it works and the latest working iteration is on the repository now. Grab it while it's hot.

Need to fix the pixel vs meters issues that are about to arise, and also fix the issues  where the entire surface of the player counts as a collision object, thus you are allowed to jump if your side or head have any contact with the world. But thats for tomorrow or the day after that.
