GLFW Chaste Tris

I have finished porting Chaste Tris over to using only GLFW as the windowing library and using legacy Open GL for all drawing. The result is a very small and very fast version which theoretically could be made to run on much older operating systems than are currently supported by SDL2.

The game behaves the same as all the other versions but does not have the rainbow text because I was trying to keep it small and simple.

This version of the game is complete. If I decide to make a moden OpenGL version of Chaste Tris I will upload it as a separate project.
