Moved to GLFW, GLEW, and OpenGL 3.3

Changed the client to use GLFW as the window handler and input manager.
Using GLEW to enable the use of OpenGL 3.3.
Many optimizations to be made, but a good placeholder for now.
Removed the player class as it was shoddily made (fk u chauncey) and
will be re-implemented later as a regular model class under a camera.
