Sonos Controller

Simple little Sonos Controller I'm building over on Github: https://github.com/nathanborror/Play/tree/ios7

I've made an improved version of UISlider that lets you drag from any location on the slider bar. This just makes it more convenient to use in practice.

The Speaker arrangement UI is still not completely thought through and a little tricky to get right. I've tried a few other permutations but nothings felt good and intuitive.

The Next Up / Queue UI is new and also not completely done but my goal is to make it dead simple to see what's coming up, add anything from anywhere, and aggregate when appropriate.
