[gnome-music/wip/jfelder/playback-status-v3: 6/10] albumwidget: Define different display modes

[Jean Felder <jfelder src gnome org>]

commit 1ef360836b872c2a012897de0b30efa81599cc0b
Author: Jean Felder <jfelder src gnome org>

    albumwidget: Define different display modes
    
    Define two separate display mode for AlbumWidget: ALBUM and PLAYBACK.
    ALBUM mode is the one already used by AlbumsView.
    PLAYBACK mode is designed to be a smaller widget: it displays less
    information (favorite status, year and composer are hidden), margins
    are smaller and there is no selection mode. It will be used by the
    future PlaybackPopover widget.
