[Owasp-webgoat] Maven build

[ch.ko123]

Hi guys,

today i transformed the build process of Webgoat to Maven. There is
still some work to do, but this was the biggest change.
Please make sure that you update your working copy, probably a fresh
checkout would be even better.
A short readme about how to build the project with maven can be found
here: http://code.google.com/p/webgoat/source/browse/trunk/webgoat/README.txt

regards

Christine
