Fix project not compiling on OS X 10.11.6.

Browse Source 
As the comment says: In Compatibility mode (used by including gl.h instead of gl3.h), OS X only supports OpenGL 2 with some extensions. VAOs, which are an OpenGL 3 feature, are not available under their OpenGL 3 name. Instead they are exposed through an Apple-specific extension that works identically in all respects that matter. With this, it is possible to build and run the program without any trouble.
