Hairo R. Carela c9e16e4888 rgnano: Sleep timer and idle poweroff support 
Actually power off the handheld with the sleep timer and idle poweroff functions instead of closing rockbox.

This commit also moves setting system volume to max from the launch script to system-sdl.c so it works when running rockbox via instant play.
