	* gtk/gtkfilechooserdefault.c (struct _GtkFileChooserDefault):
	Added toolbar items for the filter separator and the filter item.
	(toolbar_create): Add the filter widgets here.
	(filter_create): Renamed from create_filter().  Don't store the
	alignment in the impl structure, just return it.
	(toolbar_show_filters): New function.
	(gtk_file_chooser_default_add_filter): Use toolbar_show_filters().
	(gtk_file_chooser_default_remove_filter): Likewise.
	(gtk_file_chooser_default_constructor): Don't create the filter
	widget here.
	(struct _GtkFileChooserDefault): Added a field for a current
	folder label.
	(gtk_file_chooser_default_constructor): Create the folder label.
	(gtk_file_chooser_default_set_current_folder): Set the current
	folder label.

	* tests/testfilechooser.c (main): Dramatically improved the
	usability of the extra widget through careful word choice.
