Fix URLs to logo and cloudbees
Merge pull request #206 from simmel/readme-link-fixups

Thanks for the fix !

The URL for the logo seems correct (my fault, I updated jmxtrans.org without updating the this README). But the CloudBees icon seems wrong. The Jenkins build on CloudBees is outdated and not maintained, it is probably better to just remove it. I'll merge this and remove the link to CloudBees ...
