	* gtk/gtkrecentchoosermenu.c: Add support for both prepending
	and appending custom menu items.

	(gtk_recent_chooser_menu_constructor): Add a placeholder menu
	item for the empty menu case, and for giving us a starting
	point for the recent items populating process.

	(gtk_recent_chooser_menu_insert_item),
	(gtk_recent_chooser_menu_dispose_items): Insert an item at
	the position following the placeholder (and find that position
	if needed).

	(idle_populate_func), (idle_populate_clean_up): Show the
	placeholder menu item, instead of creating one each time.

	(gtk_recent_chooser_menu_populate): Kill some indirections
	and hide the placeholder before populating the menu.

	(set_recent_manager): Remember to remove the idle population
	source if the manager changes.

	* tests/testrecentchoosermenu.c: Test the appending and
	prepending of the menu items to the recent chooser menu
	widget.
