iOS: Need to trigger window menu rebuilds if a menu item changes.
Currently if code changes the checked or enabled state of a menu item it
triggers a repopulation of all menus on all windows. We may be able to
reduce this by attempting to detect which window the menu item is a
descendant of and only repopulate that menu... however this will do for now.
