    libbanshee: remove obsolete comment about 'about-to-finish' hook
    
    The callback attached to the 'about-to-finish' signal of Playbin served
    two purposes some time ago:
    a) Requesting the next track URI to banshee managed land.
    b) Setting up a timeout to fire the OnNextTrackStarting callback some
    moments after the about-to-finish signal was fired.
    
    After this commit [1] from Christopher, the purpose (b) above was not
    needed anymore because GStreamer would fire the event itself internally.
    This change would render this comment *obsolete* (but Christopher probably
    forgot to remove it) and *misleading*, the latter because the comment
    only applied to the (b) purpose above, not (a). We still need to request
    the next track URI to banshee's managed land, so the 'about-to-finish'
    signal still needs to be used (contrary to what the comment seems to
    suggest).
    
    NOTE: Christopher's commit[1] hooked to the "playbin2-stream-changed"
    event, but this has been deprecated in GStreamer in favour of the msg
    type STREAM_START. More info here[2].
