title: extend jquery ui dialog (add more options)
body: <p>how I can create and add new options for jQuery dialog?
  for example: I like that through on the setting options can control the display of title bar or display the close button.</p>
  
  <p>The script would be like this:</p>
  
  <pre><code>$("#message").dialog({
    showTitle:false,     //new option (hide Title bar)
    showCloseButton:true //new option (show close button)
    modal:true...        //other options
  })
  </code></pre>
