updates to be able to run on data
- added config files for data15, with grl and trigger options
- added variable lists for data only
- modified mc config files with empty grl and trigger fields
- added grl and trigger tools to dump-hbb
- added runNumber and modified mcEventWeight getter to be called only for MC
This is currently a WIP because it compiles and runs but gives me config warnings at run time, only when calling the trigger decision tools, and I think it's because of a missing package in CMakelists... NEW: ROOT/xAOD bug, fixed by calling LoadDictionaries.
