support for spotify podcast uris

[gad2103]

spotify has a large library of podcasts and is moving quickly in the space. it would be awesome to support playing podcast content on mopidy via a spotify uri.

Unfortunately Spotify still do not provide any way to play the podcasts on their platform. And last time I checked they still didn't provide any way to even browse them on their Web API. I don't expect they will sort this out anytime soon, they have an absymal track record. There's nothing we can do at our end.

There are hidden endpoints to access everything, someone has documented some of them on their web-api repo. I have been working with the endpoints for past few days, gonna try implement them and test.

The real hurdle is playing the podcast uris, does that work? Sadly I doubt it since libspotify predates podcasts in Spotify and without that support this can't go anywhere. So maybe try that as a priority else you might be wasting your time.

Would you be oppose to changing out libspoitfy to https://github.com/librespot-org/librespot?

I have been using Spotifyd which uses that library and it does support podcasts. Only challenge I see is having to build libraries for each platform on release.

See #110 for some previous discussion about this with regard to libspotify not being available.

This should be fixed by #342
