title: Prevent JQuery Mobile from closing a popup when user taps outside of it
body: <p>I'm using JQuery Mobile 1.2.0 alpha 1.</p>
  
  <p>Currently, when I open a popup and tap outside of it anywhere on the screen the popup is being closed. 
  I was wondering if there's any JQuery Mobile attribute I have missed which can be set and prevent closing the popup upon outside-tap? (modal popup)</p>
  
  <p>(The documentation for popups can be found <a href="http://jquerymobile.com/demos/1.2.0-alpha.1/docs/pages/popup/index.html" rel="noreferrer">here</a>)</p>
  
  <p><strong>EDIT:</strong></p>
  
  <p>I had an idea of solving this but still can't implement it to work:</p>
  
  <p>When a JQM popup show up theres a div which covers all of the screen with class of ui-popup-screen. I thought somehow to give it a large z-index and unbind all click/tap function from it. Doing this does not solve my problem but I guess it is a small step in the direction.</p>
  
  <p>Thnx in advance.</p>
