#8 First album is centered when main library is selected

[Mathijs]

When the main library is selected from another source (playlist, Last.Fm, ...) when actually playing from the music library, ClutterFlow is reset and the first album gets selected. This behaviour should be changed so that if the Music Library (or one of it's children) is the selected playback source the currently playing cover should ALWAYS be centered (unless the user is browsing of course).
