Initial commit of the PictureFlow plugin, a nice visualization for album covers.

Original code by Ariya Hidayat. Rockbox port by Jonas Hurrelmann and a few tweaks by me.
On the first startup the database is scanned and album art is searched for each album. This process will take some time (dircache enabled and/or database in RAM speed it up, and it is possible to abort by pressing MENU), but the results are cached and the next startups will be very quick.
