+
+	This function connects into the type handling of the #DbusmenuClient.
+	Every new menuitem that comes in immediately gets asked for it's
+	properties.  When we get those properties we check the 'type'
+	property and look to see if it matches a handler that is known
+	by the client.  If so, the @newfunc function is executed on that
+	#DbusmenuMenuitem.  If not, then the DbusmenuClient::new-menuitem
+	signal is sent.
+
+	In the future the known types will be sent to the server so that it
+	can make choices about the menu item types availble.
+
+	Return value: If registering the new type was successful.
