Prevent accidentally exiting a table

[jueank]

We've probably all pressed the 'exit' button by mistake at some point instead of the button next to it, which we wanted to reach, right? It would be nice if VPX had an option that prevents the player from accidentally exiting a table. Two suggestions: a) The player has to hold down the exit button for longer (1 second, potentially configurable) b) The player has to press the exit button twice in succession.
