	Bug 488507 – boundless growth of .recently-used.xbel file
	slows down applications

	* gtk/gtkrecentmanager.c:
	(gtk_recent_manager_init),
	(gtk_recent_manager_real_changed),
	(gtk_recent_manager_set_filename),
	(gtk_recent_manager_clamp_to_age): Clamp the recently
	used resources list by the age of its items, using
	the newly added GtkSettings property.

	* gtk/gtksettings.c (gtk_settings_class_init): Add the
	gtk-recent-files-max-age property, controlling the
	maximum age of the items in the recently used resources
	list.
