[Contrib: Evaluation System] Missing class deploying EvaluationSystem on 2.7.0

[Aaron Zeckoski]

Deploying evalsys 1.2.1 on Sakai 2.7.x seems to work fine for me on
OSX with java 1.6 and tomcat 5.5.27. If it is not working for other
people then I would agree that we should change the version to a newer
once.

Also, for future reference, you should be aware that the vast majority
of Sakai tools require a system restart when you deploy them.
