title: Jquery UI tooltip does not support html content
body: <p>Today, I upgraded all of my jQuery plugs-in with jQuery 1.9.1. And I started to use jQueryUI tooltip with jquery.ui.1.10.2. Everything was good. But when I used HTML tags in the content (in the <code>title</code> attribute of the element I was applying the tooltip to), I noticed that HTML is not supported.</p>
  
  <p>This is screenshot of my tooltip:</p>

  <p>How can I make HTML content work with jQueryUI tooltip in 1.10.2?</p>
