To allow more than one summary icon actor for a source we split the model of the source icon (which is iconName, if the default implementation is used, or a GIcon otherwise) and replace createNotificationIcon() with a generic createIcon(size). Also, the actual source actor is split into a separate class, that handles the notification counter automatically. https://bugzilla.gnome.org/show_bug.cgi?id=619955
