new package: rssileds daemon

rssileds is a small user-space process to control LEDs by polling the
signal quality reported by a WiFi interface. By using the iwinfo library,
rssileds is independent of the WiFi driver used.
It supports pwm controlled LEDs and may by used to nicely fade through
all colors in real-time of the rainbow while only wasting very little CPU
time and a small constant amount of system memory.
An example configuration for the ALL0258N will follow in the next patch.

This is a slightly improved version of rssileds, now quality values are
in percent and stuff is written to syslog.
