Added files for the Eclipse build-system

For now only for robospice-ui-spicelist and its dependencies.

I did not include thirdparty-libs, I think it would be best to maybe
introduce an ant-profile into the pom.xml but then other Eclipse-users
would also have to install maven just to get the repositories.

So if needed, I can add those jars with the next commit on this branch. Let me know.
