Massive reordering/sorting work. Now pretty much works.

	* gtk/gtkliststore.c (gtk_list_store_iter_changed): Massive
	reordering/sorting work.  Now pretty much works.

	* gtk/gtkrbtree.c (_gtk_rbtree_reorder): Lots of work to make
	reorder mostly work.  Still need to get the parity correct.

	* gtk/gtktreeviewcolumn.c: Listen for "model" property changed
	signal, so I can listen for the sort_column_changed signal so I
	can change my "sort_indicator" property.  Cool.
