Synchronous multi-room sound casting of Bluetooth, Airplay, Line-In and Spotitfy

ALL CREDITS TO @badaix AND @BaReinhard

This will setup a raspberry-pi-3 as a snapcast-server and snapcast-client.
Possible music sources for the snapserver-component: Bluetooth, Airplay, Spotify, Line-In (more to come eg. RTP)
Music sinks (snapclients): usb soundcard connected to my stereo, another Pi

To Do:

Energy saving by disabling onboard bluetooth, wifi and soundcard
