    discbox: Fix disc label color
    
    A previous commit fixed the style of the checkboxes in AlbumWidget by
    removing the 'content-view' css style of the AlbumWidget. This indeed
    fixed this issue but introduced a new one: the disc labels now have a
    wrong color.
    
    This new issue is fixed by updating the disc-label css style. The
    DiscBox activatable property is also set to False to prevent a color
    change on DiscBox hover.
