PATPackedGenParticleProducer: cut on abs(eta), not eta
wMINIAOD event content: remove explicit process name from keep statements (in particular, the process names for l1 information were wrong, so the objects were not kept)

Conflicts:

changing input collection for tauGenJets in miniAOD
fix electron source PFCand pointers
equivalent fix also for photons
fix saving of photon mother and add mother of eles with pt > 3
add rekeying of daugthers in genJets using the packedGenParticles as target
fix the keep statement for proton and summary particles to void adding 100 more gluons
do not store the new association, saves 270bytes/ev
set numberOfMothers to 1 for packed gen
better with a ref validity check
add some secondary vertex information in jet user floats
PackedGenParticle: add a method to get the edm reference to the mother
JetMETCorrections/Type1MET: CorrectedPFMETProducer: carry over significance to corrected MET (https://hypernews.cern.ch/HyperNews/CMS/get/csa14/11.html)
pat::MET: add to the sent of uncertaintes also the central value. A better implementation of the whole pat::MET corrections (independent from the uncertainties, and more similar to the one of pat::Jet) would be better, but would be a much more intrusive change, while this one is minimal and preserves compatibility
