fixed PF2PAT module names (added missing 'JME' string)
commented out unused parameter in the GenJetMatcher configuration
fixed problem with re-enabling b tagging in switchJetCollection() once it has been disabled
fixed adaptPV() (currently it was skipping b-tagging modules and modules
like pfElectronsFromVertex and pfMuonsFromVertex), also turned it into a more generic tool
