//------------------- Changes -----------------------
// August 23rd, 2007: 2.0
// * Added cleanup of Kontera popups (previously only handled Intellitxt).
// * Now Use XPath to reconstitute text broken up into separate text nodes.
// * Added checking for telltale script elements before adding the event 
//   listener to try to avoid bogging down sites that do a lot of DOM node
//   insertions but do not use text popups.
// September 20th, 2007:2.1
// * Added hasAttribute check for script element src attribute before getAttribute call
