title: Adding hover event to elements inside a tinymce editor
body: <p>I have a tinymce plugin that populates the editor with content.</p>
  
  <p>Certain populated elements have a class="hoverable"</p>
  
  <p>I'd like to attach a function to the hover event on those elements with class="hoverable"</p>
  
  <p>I know how to attach an onClick with ed.onClick.add in the create function but there is no ed.onHover.add or ed.onMouseIn.add.</p>
  
  <p>Edit:
  My plug-in actually pops up a dialog when you press the plug-in button in the menu. The user selects some content from the dialog and inserts it into the editor.</p>
