Add snapcast for multiroom audio

[Yannovitch]

It would be great to add snapcast to your project to be able to add multiroom capabilities to the other software such as Mopidy

When developing musicbox I also searched for a solution for multiroom audio and thought about snapcast and other multiroom solutions. I did a test with snapcast but was very disappointed about the result.

Unfortunately I do not have the time to actively develope the musicbox any more. I only did some bugfixes and upgrades of the main OS.
You are free to fork this project and do your own development.

Maybe - if I find the time, I will try snapcast again (maybe it is better now :). I will get you informed, when a integration is possible.
