Allow touch handling of mouseover menus

Use the aria-haspopup property for the Tools button to indicate that it has hidden hover content, so that IE 10 and greater simulates a hover on the first tap, rather than activating the link. I guess this is needed for the Add button also, but it may change the default action for non-touch,
