[Rivet] CMS jet multiplicity in ttbar->lepton+jets (8TeV)

[Markus Seidel]

Hi Rivet authors,

congratulations to the new release!

Unfortunately, it missed CMS_2016_PAS_TOP_15_006. Could you put that in 
the next release, please?
The result is PAS-only as the author left the field before finishing the 
paper.

Cheers,
Markus
