Spotifyd via camillaDSP: Success :-)

[findnix]

Thanks @rern for integrating the new spotifyd.
Spotify is now running smoothly for me, and switching between mpd and spotifyd is also working reliably.

As I am a big fan of room correction via camillaDSP (convolving filter, created with REW), I tried to have spotifyd write to loopback and was successful.

Unfortunately, /etc/spotifyd.conf has to be adjusted after every restart or update. But I am happy to accept that, especially since I always had to change the default settings anyway because of my Pro-Ject DAC.

Thanks again for your great work and greetings from Austria,
Ronald
