title: How do I get the jQuery-UI version?
body: <p>This should be an easy question, but how do I detect the jQuery-UI version?</p>
  
  <p>This is for a Greasemonkey script and the (current) target page appears to be running jQuery-UI, 1.5.2.  But, different target pages may run different versions.</p>
  
  <p><code>console.log ($.ui);</code> did not show anything useful/obvious for version detection.</p>
