Speed (and sanity ;) optimization:
Until now the launcher parsed qpe.conf, open the ts device, set the
backlight with an ioctl and closed the device again on *every* keypress or
stylus tap.
This is only done now, when it is really necessary (~1% of all cases).
Additionally this allows easier integration of the iPAQ light-sensor.
