	* gtk/gtkuimanager.[hc] (gtk_ui_manager_add_ui_from_string): Use gssize
	for length, not gsize.

	* gtk/gtkuimanager.c: Refactor the XML format a bit: rename <Root> to
	<ui> and make it optional in strings. Rename verb to action, <dockitem>
	to <toolbar>, <menu> to <menubar>, <submenu> to <menu>.

	* demos/gtk-demo/appwindow.c:
	* tests/testactions.c:
	* tests/testmerge.c:
	* tests/merge-1.ui:
	* tests/merge-2.ui:
	* tests/merge-3.ui: Adjust to the new XML format.
