S2P WIP updated!

Together with the "Black" theme, the S2P all song list will have a new look like this. Although S2P will take a little longer to start (e.g. for more than 1,300 songs / 120 albums, S2P takes 0.2 second longer than the current version to start on a HD2), it's worth to have the ID3 embedded title, artist & album name shown.
