Automatic Jenkins builds for pull requests

[Christian Schneider]

Apache Artemis is doing automatic jenkins runs for all pull requests. I 
think this is really helpful as the contributor gets some good feedback 
about the state of his request.
It also lowers the work of the committers as they can wait until the 
pull request is in a good state.

If no one minds I will also install this for karaf.
