[LumenRT] FR:Kiosk mode

We are missing kiosk mode for LumenRT so the livecube can be left unnatended for any visitor to navigate in LiveCube and not only as animations. Ideally with touchscreen support.

Idea would be that Livecube is left opened on computer and any who is interested can use it. There should be an option to reset the scene after some timeout and a button/command line option(scheduled task?) to restart the scene or run default animation after some time. Now it is more oriented to advanced users so the LiveCube needs to be shared as file and run on capable hardware but for demos it would be easier to set it as ready to use kiosk machine.
