title: Jenkins and Github with forked pr commits
body: <p>I'm having an issue setting up Github and Jenkins CI. </p>
  
  <p>When a forked PR commits changes, github doesn't notify jenkins, even if I've accepted the PR from a forked repo. Only when I merge a pr from a forked repo into master will github trigger Jenkins.</p>
  
  <p>So the credentials and ability is there, but I can't find the option in github to force ALL commits to the original repo (including forked pr's) trigger the CI, anybody any suggestions?</p>
