Automatic backlight control

[Buri]

I repurposed code from orientation and and generic_buffer. Still work in progress, more of proof of concept.

Future milestone: split to standalone driver and backlight controll connected via dbus

I pulled this.

However, I'm getting a segmentation faultwhen I run it.

It happens because of access rights to backlight control. It requires root acces to read/write /sys/class/backlight/intel_backlight/brightness.
