Save ratings to external file

[calderino]

Would it be possible to have the ratings stored in an external file, like it is done with the cover.jpg?
Something like ratings.txt

When seeding torrents, the hash of the file needs to stay the same, and rating the tracks changes this.
I could store them in my Musicbee database, but I would prefer to have them outside of the Musicbee ecosystem in case of an issue (and to keep backups easier).
