Create a new Game Engine

[mrjatkin]

Create a new game engine, with a custom made canvas module built in, that uses WebGL and falls back to using canvas. By doing this, we can make lots of performance improvements and address the following issues:

• Support retina screens #17 Support retina screens
• Swap Box2dWeb for the original C++ version of Box2D, compiled to javascript using Emscripten #18 Swap Box2dWeb for the original C++ version of Box2D, compiled to javascript using Emscripten
• Add 2d lighting #61 Add 2d lighting

The new engine and canvas module should automatically support retina displays. Retina scaling should be done automatically to reduce bugs in the game's code. We should not have to deal with scaling outside of the new game engine.

I've decided to make this my main priority for the moment

To remove the dependency on the Class library, improve readability and reduce the risk of bugs in the code, I'm using TypeScript for the new engine. This means that you all know the majority of the language already, because it's a superset of JavaScript.
