[chrispap95]

The title says it all. I also removed one of the two patches since the change has now been merged upstream. More information on the new releases:

• FastJet v3.4.1: http://fastjet.fr/all-releases.html#3.4.1
• fastjet-contrib v1.051: https://fastjet.hepforge.org/contrib/contents/1.051.html
