Title: Generator Interface backports for Pythia 8, LHE input, jet matching

Pythia 8 interface and LHE interface/input have been brought fully up to date with 7x series. Jet matching is targeting pythia 8 internal matching/merging. "Legacy" matching interface has not been touched. (So Pythia 6 and fortran ME2pythia behaviour should be completely unchanged)

Needs to go in together with update to Pythia 8.200pre2

In order to be strictly a backport, the last pull request should be merged into 73x first in principle:
