SLB: Complete the Hb -> Hc lines, also adding them for electrons

Add remaining Hb -> Hc lines for muons and all of them for electrons. In both cases following very closely the already existing lines with muons / tauons in the final state. The cuts for electrons have not been modified yet with respect to the muon selection, this will wait for efficiency studies.

For these decays, also a selection with "fake electrons" is defined. "Fake electrons" are selected with reversed PID (i.e. PID_E < 0.0) and required to be in Ecal acceptance.

The Hb -> Hc lines are grouped into HbToHcLNu.py and HbToHcTauNu_TauToLNuNu.py The definitions for electrons and muons happen in the same function, configurable with lepton="mu" or lepton="e". Line instantiations all happen in hlt2_semileptonic.py, where electron and muon lines are defined separately.
