Summary

Adds the sources of easy-unit to the repo

Focus

• The 0.0.1 version of easy-unit has been releases by it's maintainers and so we can use that one from now on.
• The server-repo should have three easy-unit jar-files now:
  1. The compiled classes
  2. The javadoc
  3. And the sources (new!)

Test Environment

Please extract the sources jar-file and confirm, that the sources are in there
