Changed GUI to be instanceable (rather than just one GUI per project). GUI.start() is now var gui = new GUI();

Included prettify.js in the repo so people checking the demo localy doesn't need the internets.
Changed way of hidding the panel (controllerContainer.style.height rather than this.domElement.stylemarginTop).
