Fix theory systematics and 4FS/5FS overlap removal; various changes
- Complete (and now include here) the list of samples with missing/buggy PS and/or QCD scale weights. Also fix: systematics were not properly removed for samples with subprocesses
- Fix postprocessing of systematics from alternative samples (normalize, copy histograms to nominal files, removal from plotIt list)
- Fix muon HLT paths for 2016 samples
- Fix label ("electron", "muon", "lepton") on summed plots
- Change default job runtime from 4h to 6h
- bTagPlotter: compare 3D with 2D ttH b-tag patches
- Fix application of 2D ttH b-tag patches for ttbb components
- controlPlotter: make backup of batch results folder before running (possibly destructive) postprocessing. This should be extended to other plotters as well.
