widget/RichText.js - document.write unnecessarily wipes page

Description

RichText widget does a document.write() which ends up overwriting the entire page if the widget is loaded dynamically after the page has been loaded. This document.write can be avoided.

Possible Fix:

Possible test case using Editor which requires RichText: 

<html>
<head>

<script type="text/javascript" src="dojo.js"></script>

<script type="text/javascript">

function doMakeRich()
{
  dojo.require("dojo.widget.Editor");
  var editor = dojo.widget.fromScript("Editor", {}, 
                                    dojo.byId("california"));
  
}
</script>

</head>

<body>
<div id="california">I live in on the West Coast.</div>
</body>

<script type="text/javascript">
setTimeout("doMakeRich();", 4000);
</script>

</html>

I don't believe this is an issue with Editor2. Please verify and close.
