Instead of having _compareItems, _getItemId, etc. on the view to pull out info about items, use the AppIcon / FolderIcon items we create as a place to track this additional info. We now require that these items have a '.id' property for deduplication, and a '.name' property to sort by. https://bugzilla.gnome.org/show_bug.cgi?id=722117
