	Fixed bug I introduced in my last sorting change (sort order
	was incorrect when nodes are first inserted):

	* components/tree/nautilus-tree-view-private.h: added an
	`inserting_node' flag field to the view details. This is used
	to tell the sorting comparison function when the nodes it's
	trying to sort haven't yet been fully initialized

	* components/tree/nautilus-tree-view.c
	(nautilus_tree_view_insert_model_node): set the inserting_node
	flag around the call to nautilus_ctree_insert_node (). After
	the node is fully initialized, call
	nautilus_ctree_sort_single_node ()

	(ctree_compare_rows): when `inserting_node' is set, bail out
	with a nonsense value

	* libnautilus-extensions/nautilus-ctree.h,
	libnautilus-extensions/nautilus-ctree.c: reverted the change to
	insert_node
	(nautilus_ctree_sort_single_node): new function, reorders a
	given node, but no others
