title: Get paste event for WYSIHTML5
body: <p>I have an WYSIHTML5 editor and I wrote a paste handler to paste images in site, as attachments. The problem is that I want the pastehandler to work when I hit paste inside the WYSIHTML5 editor also. </p>
  
  <p>I've registered to paste event like this</p>
  
  <pre><code> this.editor.observe("paste", this.pasteHandler);
  </code></pre>
  
  <p>but the problem is that my pasteHandler needs the event that fired it as a parameter, but the observe function it's not sending the event. </p>
  
  <p>How can I send this event from WYSIHTML5 editor to my paste handler?</p>
