Traceurl goes GWT 2.0

I finally managed to update the traceurl.com website to GWT 2.0 (2.0.4 to be precise). Up to now traceurl.com was compiled with a GWT 1.5 compiler. This update should fix a couple of issues with IE8 and bring some overall improvements in performance. The update path was quite smooth, although I had to fiddle with some third party libraries. Let me know in case you experience any problems...
