EITopPAG updates, merging with E/Gamma features

[rappoccio]

Here is the full request for the changes to EITopPAG that were requested. This merges a few topics :

1. Adding only b-tagging to the EITopPAG but nothing else (Adding b-tagging only to the EITopPAG #678)
2. Adding the e/gamma changes to the GsfElectron (Porting changes for beaudett: was pullID 120 #156)
3. Adding Volker's fixes to make it compatible (70 x fix for156 #666)

And finally this has a few additions of its own to bring everything together:

1. In PFElectronTranslator, the isolation from pileup is actually filled. I also fixed a bug from topic branch 666. The python file was not in sync with the EDProducer for the names of the isolation variables.
2. And of course, I changed EITopPAG top projection to use the updated variables.

All tests in CommonTools/ParticleFlow/test/ are broken. Nothing is run in IBs, but it should be fixed nevertheless.
However, that does not defeat the purpose of this feature branch.

Hi

I ran the tests on top of CMSSW_7_0_X_2013-09-02-0200, all tests passed

base release CMSSW_7_0_X_2013-09-10-0200
incremental reference CMSSW_7_0_X_2013-09-10-0200 + #666

Compared to base + #666, observe changes only in EI branches, consistent with the changes in pt and isolation cuts.
Comparison of #680 with the base shows an additional difference in the pfPhoton plots for conversions in the 19.0 workflow (gamma-35GeV), consistent with the change in the associator used in photonValidator_cfi.py

This pull request is fully signed and it will be integrated in one of the next IBs unless changes or unless it breaks tests.
