Emscripten Test

This is just a test. The game is not playable. This is a test at converting C/C++ projects to HTML5/JavaScript using Emscripten.

I had to use GLES instead of the normal OpenGL core profile. Because of this I had to simplify the shaders, but I still achieved the same effect as in the original C/C++ project. For example glsl version 100 es doesn't support the modulo operator, %, which I used for the shader to draw the font. I had to use division and floor() to get around this.
