Binary PLY File Support

I’ve just added support for binary files to my PLY file reader. With this enhancement on board I could render the heavier models from the Stanford 3D Scanning Repository.

Thai statue (10 million triangles)

I ran out of luck with the Lucy model, though, as the core engine would run out of memory (I have 3GB installed and compile as a 32-bit app) while constructing the kd-tree…. 28 million triangles is heavy, and my code for kd-tree construction is probably not the most memory efficient out there.
