Test project for moreUnit

Started to create a test project for moreUnit (org.moreunit.test) to reduce dependencies.
It took me while to figure out how it works.
Short summary:

• Create a plugin-project without content
• Copy plugin dependencies from MANIFEST.MF
• Add org.moreunit as a plugin dependency
• Needed to export the moreunit-packages ('Runtime'-tab in plugin.xml)
