title: wp_list_pages adding title to LI class
body: <p>is there a way to add the Link page title to the LI class?  I am trying to generate the navigation using wp_list_pages and would like each link to have its page title in the LI class next to page-item.  I have to style each li individually for background image hover.</p>
  
  <p>Been searching but no luck =(</p>
