Extension from Thunderbird to Shredder

I now updated my extension to also work with Shredder (the Thunderbird3 beta).
Seems like - again - the internals of the mail popup menu changed:

• First of all the user agent now reports "Shredder" instead of Thunderbird.
• Then - after a lot of debugging - I had to replace the
  document.popupNode.getAttribute('emailAddress')
  with
  document.popupNode.getAttribute('text').
• Problem there is , that text contains more then just the emailAddress used to, and I had to parse it...

And XUL on Thunderbird/Shredder is still not easy to debug.
