    playlistdialog: Make dialog insensitive while creating playlist
    
    When creating a playlist, the current behavior gives no feedback that
    the operation is going on, neither blocks the user from repeatedly
    click the Add button. This may lead to confusion and errors.
    
    Fix that by making the entire dialog insensitive while a playlist
    is being created.
