title: jquery dialog without jquery's style\classes
body: <p>I have my own styled form, and I wanna use jQuery UI's <code>.dialog()</code> in order to display it with an overlay, and as a modal dialog.
  Problem is, jQuery enforces its own classes and styles, such as:</p>
  
  <pre><code>ui-dialog ui-widget ui-widget-content
  </code></pre>
  
  <p>Is there a simple way for me to instruct jQuery not to use its own css ??</p>
  
  <p>Thanks!</p>
