[PATCH] Ajax.InPlaceEditor.getText. Patch for entity reference

Hello!! From Japan.

I hope patch like this:

638: getText: function() {
-639: return this.element.innerHTML;
+639: return new String(this.element.innerHTML).unescapeHTML();
640: },

or

638: getText: function() {
-639: return this.element.innerHTML;
+639: if(this.element.childNodes){
+640: return this.element.childNodes[0].nodeValue;
+641: }else{
+642: return ;
+643: }


In the case of most, html contents is written using entity reference.
Example:
<span id="inplace">ABC&amp;XYZ</span>
<script>
new Ajax.InPlaceEditor('inplace',....


if there are no patch, "&amp;" is displayed in input-area.
I expected "&" was displayed.


My English is clumsy. Sorry & Thank you for your time.

This is a dupe of #4588 but I personally prefer this patch because it only modifies one line
