Changed L1 emulation sequence to be compliant with postLS customisations
(changes agreed with A. Perrotta, A. Gammanco, L. Vanelderen):
- Import L1 emulation modules from SimL1Emulator_cff
- Use "sim" labelled modules for L1 emulation but keep gtDigis and l1extra particles naming as they are (interface to HLT)
- Update HLT .py to customise menu dump from confDB accordingly
Updated FastSim menu dumps according to A. Perrotta's instructions
