SusySelectionMatt::getBTagWeight: 2.4 -> JET_ETA_CUT_2L (same as SusySelection)
SusySelection: provide static versions of passTrig2L*
MeasureFakeRate2::passConvCR : clarify we are just transforming a vector
bugfix: SusySelection::passTrig2LwithMatch was making a recursive call
drop SusySelectionMatt::passTrigger, call SusySelection::passTrig2LwithMatch

Details:
note that the passTrigger counters are now different, but they were
wrong anyway (the dilepton type was not being updated correctly).
The contents of the histograms however are still the same.
