	* gtk/gtktreesortable.c (gtk_tree_sortable_set_sort_func): Rename
	gtk_tree_sortable_sort_column_id_set_func.  It's much shorter now.
	* gtk/gtktreeview.c (gtk_tree_view_sort_iter_changed): WOOO!!!
	Now I can really reorder/sort all Store widgets.  treesorttest
	seems to just work now.
	* gtk/gtklistview.c (gtk_list_store_iter_changed): Whoops.
	testtreesort worked through a big coincidence all this time.
	* gtk/gtkrbtree.c (_gtk_rbtree_reorder): Nasty bug fix in nasty
	code.
	* tests/testtreecolumns.c: Big 'ol warning at the top letting
	people know that this code should never ever ever be copied.

HA!

While everyone else was busy flaming eash other over configuration
engines, I secretly got sorting completely working with store widgets
and GtkTreeView.  GtkTreeModelSort, here I come!!!!!
