Backup sources and improvements 

I already have a "dumb import" (retag all files based on the filepath)
so there is no point in storing extra attributes when I am only going to
find them again during importing.  Instead, we should only store the
information we need: filepath, score, and playcount.

Additionally, I now store the list of sources in the library backup.
