title: jQuery UI tabs, update url when clicking on a different tab
body: <p>I'm using the tabs of jQuery UI: <a href="http://jqueryui.com/demos/tabs/" rel="noreferrer">http://jqueryui.com/demos/tabs/</a></p>
  
  <p>How to update the current url of the <strong>browser</strong> when the user click on a different tab by adding the anchor link to it:
  <em>ex: url.html#tab-4</em> and pushing the current history of the browser at the same time.</p>
  
  <p>Thank you!</p>
