Changed to have the list become non-italic when the demo window is

Sat Nov 18 18:00:17 2000  Jonathan Blandford  <jrb@redhat.com>

	* demos/gtk-demo/main.c: Changed to have the list become
	non-italic when the demo window is destroyed through an external
	event (like a close button).  Doing so found three bugs in the
	widget.

	* demos/gtk-demo/*.c (do_*): Changed to return the toplevel window.

	* gtk/gtkliststore.c (gtk_list_store_set_cell): emit "change" when
	we actually set the cell.

	* gtk/gtktreestore.c (gtk_tree_store_set_cell): ditto

	* gtk/gtktreeselection.c (gtk_tree_selection_real_select_node):
	free a leaked path.  Thanks memprof.
