    Pluralize tooltips with multiple selection
    
    Looks like when we went to the pill toolbar, we lost our plural tooltips
    on the toolbar.  This hooks up to the tooltip changed signal to keep the
    buttons in line with the action, which we're setting from the
    controller.
    
    Closes: bgo #720710
