    playlistview: Select a random song in ShuffleMode
    
    By default, when a playlist is launched from the play button, the
    first song is chosen and the playlist starts. However, if the player
    is in ShuffleMode this does not seem right: a random song should be
    selected.
    
    Fix it by picking a random row if the player is in ShuffleMode.
