Help for finding the current URI

[Gudsfile]

Problem

Not all URIs are well documented, so it is difficult for some sources to identify them. This makes it complicated to add discs to the library.

Problem encountered while working on the documentation for the examples #275.

Proposed change

Add a feature that displays the current URI. This would allow users to simply play the desired song to find its URI and add it to their library.

sonos.get_current_track_info()['uri']

[Gudsfile]

The problem is that the current URI corresponds to the music that is currently playing, not to the desired collection (album, playlist, radio station, etc.).

I don't know how to go about it. I need to think it over.
