Beginning of the next version...

THIS IS A REAL-DEAL BREAKING CHANGE

I've had this version kicking around a private branch for a while. Audio player and lightbox stuff is backwards compatible but we've been working on a much improved embed workflow that will not work with the current beta version of the platform. It *does* work with the current version of things in cashmusic/platform so I'm pushing it in there. 

We'll likely make a few additional changes before blessing this version and pushing out to CDN.
