Improve robustness to network failures for get mpd status
If over 50 items, the play queue will nicely display a fastscroll. Fixes #349
Lists will show fastscroll using inset everywhere, and not only on API 19 anymore. I like consistency :)
The album grid does not use a ArrayIndexerAdapter. It didn't even really work since a grid does not behave like a list
Songs fragment does not need an ArrayIndexerAdapter, neither does it need a fastscroll.
Use default scrollbar style for SongsFragment
add if artist is albumartist to Album Parcel
