Building Robocode

Please be aware that you need to use Maven 2, not 3 to build. Just had to debug maven to find out why it would not run. Also mvn.cmd will mess with you trying to execute mvn from your path. i would recommend renaming mvn.cmd to mvn_.cmd I have tried migrating the poms to 3, but not had much luck, backed out and switched back to maven 2.
