Initial Commit:  Plugin works for my single speaker system. I attempted ...

...to build it for multiple speaker systems, but I have no way to test/troubleshoot it.

I'm not sure if this fits your programming style, but I tried my best.  I would love for someone with multiple speakers to test/add to this.  It may be a little while before I add speakers to my system.

The main purpose of this for me is to link it with my DIY home automation system.  I wanted to contribute to what I feel is a great project instead of just branching out on my own.
