PictureFlow: remember inspected album artwork

Browse source 
Each time PictureFlow was launched, it would rebuild the
album artwork cache from the beginning.

Depending on the number of albums, this could take a while
and resulted in choppy scrolling.

PictureFlow will now remember how many albums have been
inspected already, and only rescan and write new artwork
when the album index cache gets updated or rebuilt.
