	Bug 324282 - add selected signal to cell renderer combo.

	* gtk/gtkcellrenderercombo.c (gtk_cell_renderer_combo_class_init),
	(gtk_cell_renderer_combo_changed),
	(gtk_cell_renderer_combo_start_editing): add a new "changed" signal
	that will be emitted as soon as the combo box emitted changed and has
	an active iterator.  (Modified patch based on work by James
	Pelletier).

	* gtk/gtkmarshalers.list: add marshaler.
