Add support for iggli

I see that there is already a request to support my friend's, Daniel Ek's, service Spotify. I know Spotify is widely available in Europe (and not so much in the US). But I suspect Spotify will find its way to the US by the end of this year or early next year.

I'd also like to see Twones integrate with iggli. See iggli.com/partners/. I'm iggli's CEO.
