	Provide access to the string representation of accelerators used
	in GtkAccelLabel.  (#154068, John Spray)

	* gtk/gtkaccelgroup.h:
	* gtk/gtkaccelgroup.c (gtk_accelerator_get_label): New function
	to return the accelerator label used in GtkAccelLabel.
	(gtk_accelerator_name): Update docs to point to
	gtk_accelerator_get_label().
	* gtk/gtkaccellabel.h:
	* gtk/gtkaccellabel.c (_gtk_accel_label_class_get_accelerator_label):
	New auxiliary function which creates the string representing the
	accelerator.
