Filter for events with HCAL-calibration laser firing is applied for real data only

The filter is intended to be used with a re-reco of real data and fails in simulated events. It checks some trigger conditions and, therefore, does not bias kinematical distributions and can be ignored in simulation.
Run-time bugs in MC caused by missing modules in the path have been fixed
Several MET-related modules missing in paths for real data have been added
Default event selection changed

Instead of at least one jet with pt > 40 GeV/c, now the configuration requires at least two jets with pt > 30 GeV/c. Documentation for jet definition has been improved a bit
Jet ID has been updated

Jet ID now accounts for the change in definition of hadron energy fraction described in [1].
