	* tests/testmerge.c (add_widget): Put toolbars in handleboxes.

	* gtk/gtkuimanager.[hc]: Add a boolean property, "add_tearoffs" with
	setter and getter. If it is set, add tearoff menu items to regular
	menus, but not to popups. Add a signal "changed", which gets emitted
	when the merged ui has changed.

	* tests/testmerge.c: Add button to test the generation of tearoff
	menu items.
