2D rendering!!

I have to admit this feature was kinda easy to implement, because most of it was ripped straight from my last game engine, but I did it because I think it is a really smart way of handling how a 2D system should work. Everything relies on the Surface class, the display itself is a surface, the loaded images are surfaces, and those surfaces can draw to eachother. This makes the system easy yet expandable. I think it’s kinda cool. It was heavily inspired by how pygame does things.
