Updated version, following the opengl-tutorial.org tutorial
Continuing through tutorial, including text and lighting.
Starting to separate things out into an engine and code to run the engine.
So far, GLFWWindow has been wrapped.
Continuing RAII-ification.
Moving the OBJ-reader, VBO-builder into a separate class.
Added cleanup of NG::VBO objects,
  removed objloader and vboorder files.
Moved loading of uniforms into the NG::ShaderProgram class.
Moving Textures into a RAII-ified form, NG::Texture.
Moved Text2D into a nicer class.
Moved GLFW/GLEW initialization to the NG::Window class.
Support for multiple windows is questionable,
  since most of the initializations are context-specific.
Switching to using the existing library SOIL.
Adding the assimp library instead of my own custom OBJ loader.
This handles more formats, yay!
Cleaning up the scons configuration.
