[PROBLEM] RPi3 wont turn off CEC TV with delay from xbian config

[Nachteule]

Unfortunately this function was removed some months ago (the code was in /etc/init/xbmc-screensaver.conf and currently this script does nothing).

I suppose there were 2 reasons doing this:

1) nobody (expect me?) used this function
2) it was announced that future releases of CEC library does not support multiple clients anymore (see here)

So I wrote my own /etc/init/xbmc-screensaver.conf but this requires patched Kodi to make it work again
