Hi,
I finished to write the code implementing the automatic backlight
reduction after a given time of inactivity (that can be set in the
backlight menu). The patch is relatively straightforward but reviewing
is always welcome so fire up. To have the automatic backlight just set
the Dimming time to a non zero value. The automatic dimming is disabled
when the dimming time is 0.

author : Mathieu Taillefumier (mathieu.taillefum...@free.fr)
Add automatic backlight dimming.
- two parameters are added :
- sleep backlight is the backlight minimum during extensive inactivity
time (6 min)
- dimming timeout : Time of inactivity after what the backlight is
reduced to the idle backlight intensity
