Fixes issue #3576 * Clouds now take camera position as 3D, not 2D * Cloud grid filling extracted to gridFilled method * Clouds detect whether camera is inside cloud * Camera in cloud changes fog by overriding sky colors with cloud color * Sun, moon and stars can be temporarily disabled with setBodiesVisible * Disabling fog also disables all "inside cloud" behaviors
