feature request: store track_mbid

[nemethf]

Would it be possible to store some of the additional info sent by a listenbrainz client? I don't request to do anything with the data. But if at least the track_mbid was in the database, I would have a theoretical possibility to more easily write a tool some time in the future that analyzes the scrobbles in a different manner than currently available. Thank you.

Implemented! Do you know a scrobbler that submits these so I can test it?

Quodlibet's listenbrainz plugin does submit these. However, it doesn't work out of the box and doesn't allow to change the api_url. (I plan to create a proper PR from my local modifications. I now just hardwired the api_url of my local maloja.)

I've briefly tested the new code and it seems to work just fine. The additional info is saved in the 'rawscrobble' and the 'extra' fields of the 'scrobbles' table.

Thanks again
