[GLExtensions] Initial code drop for GLExtensions. This drops GLEW entirely from the codebase. This has been tested on Android and Linux+ATI. Of course untested on Windows and Apple. Also untested with Linux + EGL but should be fine there. There are most likely a couple of extensions I'm missing which would result in null pointer runs but not bad for the initial commit.
