MVA Photon ID

* Updated the mono-jet configuration macros/runMonoJet.C to use the latest and graetest MVA photon ID developed by Mingming and the recommended photon energy regression.  Both of these are specific for the non-run-dependent 8 TeV MC. You need the HEAD of cpausmit/MitPhysics.  So please pull the recent update from this Monday do `scram build`. WARNING: This will probably not work with the "new setup" where you can submit jobs to the Tier2, see comments to cpausmit/MitPhysics#6
* Removed corrections and MC smearings derived on the Z->ee data as agreed with the Bacon guy(s) (Phil :-)).
