Screen blanker config

[andy pugh <bodgesoc@gmail.com>]

Our ISO image is intended for a CNC controller. It is important that
the display never blank or automatically log-out the current session,
even if left for days at a time with no user input.

Can anyone give me any pointers how to achieve this in a live-build image?
