Fog effect when camera is inside cloud

Browse source 
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
