Added several script calls so you can change resolution, full screen via script call command.

• setResolution(index)
  • Change to a specific resolution by index (0 = first, 1 = second, etc.)
  • Example: setResolution(2);
• nextResolution() or previousResolution()
  •  Cycle to the next/previous resolution in the list in parameter
• setFullscreen(state) or just setFullscreen() to toggle
  • State can be true/false
