Support 'automatic track replacement' in Spotify playlists

[jodal]

As of the April 2010 releases of Spotify they support "automatic track replacement":

Automatic track replacement: Spotify will now automatically try to find a replacement for any track you can’t play. So if a friend in another country sends you a playlist with tracks you can’t play or a local file, we’ll search our catalogue and link to a playable track when possible. A ‘link’ icon next to the track name represents replaced tracks.

Currently, Mopidy cannot play these tracks and just prints e.g.:

WARNING  Play spotify:track:6R81HhHxetvaWqQoM9K4Ll failed: The track cannot be played

As far as I can see from the API docs, libspotify can tell us that this is a autolinked to another track: http://developer.spotify.com/en/libspotify/docs/group__track.html#g4eeb86de13187697cd9dfe0b0934988d

This can be implemented by turning on autolinking in each libspotify playlist as it is loaded. See http://developer.spotify.com/en/libspotify/docs/group__playlist.html#g16481ebc3ea46d0e57e650ca7bf335b5 for details.

The develop branch of pyspotify now supports this. Will be in 1.3 release.

This is fixed in pyspotify by always have it enabled. The feature is available when v1.3 of pyspotify is released.
