Include electron scale factors

Use scale factors presented in this talk [1]. Their uncertainties cover
the degradation of trigger efficiency in runs affected by
misreconstruction of the online beam spot [2], and thus this portion of
data is now included. As a consequence, pile-up profile in the electron
channel is also updated, and now it's virtually indistinguishable from
the one in the muon channel.

 ## LeptonSF
 
- * `ElectronSF_2015D_76Xv1.root` <br />
-   Scale factors for electron reconstruction and tight working point of cut-based ID. Adapted from [here](https://twiki.cern.ch/twiki/bin/view/CMS/EgammaIDRecipesRun2?rev=16#Electron_efficiencies_and_scale). The histograms are parameterized with electron transverse momentum and pseudorapidity of the associated supercluster. No appropriate scale factors are available for single-electron triggers.
+ * `ElectronSF_2015D_76Xv2.root` <br />
+   Scale factors for electron reconstruction, tight working point of cut-based ID, and trigger `Ele23_WPLoose_Gsf`. First two are adapted from [here](https://twiki.cern.ch/twiki/bin/view/CMS/EgammaIDRecipesRun2?rev=16#Electron_efficiencies_and_scale). Trigger scale factors are taken from [this talk](https://indico.cern.ch/event/491510/contributions/2246475/attachments/1310813/1962318/2016.07.18_EGM_Electron-trigger-SF_v2.pdf). The histograms are parameterized with electron transverse momentum and pseudorapidity of the associated supercluster.
  * `MuonSF_2015D_76Xv1.root` <br />
    Scale factors for muon identification and isolation (tight working points in both cases) and triggers `IsoMu20 OR IsoTkMu20`. Adapted from [here](https://twiki.cern.ch/twiki/bin/view/CMS/MuonReferenceEffsRun2?rev=9#Results_for_CMSSW_7_6_X_dataset). Histogram errors are updated to include the additional uncertainties recommended by the reference. The trigger scale factors derived for Run2015D are combined taking corresponding integrated luminosities into account; Run2015C is ignored. No scale factors for `IsoMu18` are available.
 
 
 ## PileUp
 
- * `Run2015D_SingleMuon_v2_finebin.root`, `Run2015D_SingleElectron_v2_finebin.root` <br />
-   Profiles of pile-up in data collected in Run2015D. They are constructed as described [here](https://twiki.cern.ch/twiki/bin/viewauth/CMS/PileupJSONFileforData?rev=22#2015_Pileup_JSON_Files), using an effective minimum-bias cross section of 69 mb. The "golden" certification file was used. In case of electrons, runs with wrongly reconstructed online beam spot (listed [here](https://hypernews.cern.ch/HyperNews/CMS/get/physics-validation/2556.html)) are excluded.
+ * `Run2015D_SingleMuon_v2_finebin.root`, `Run2015D_SingleElectron_v3_finebin.root` <br />
+   Profiles of pile-up in data collected in Run2015D. They are constructed as described [here](https://twiki.cern.ch/twiki/bin/viewauth/CMS/PileupJSONFileforData?rev=22#2015_Pileup_JSON_Files), using an effective minimum-bias cross section of 69 mb. The "golden" certification file was used.
  * `simPUProfiles_76X.root` <br />
    File with simulated pile-up profiles for the `RunIIFall15DR76` campaign. Only includes the nominal profile taken from [this configuration](https://github.com/cms-sw/cmssw/blob/CMSSW_7_6_4/SimGeneral/MixingModule/python/mix_2015_25ns_FallMC_matchData_PoissonOOTPU_cfi.py).
