New Run1 simulation GT for HCAL response corrections.

New Global Tags for Run1 simulations (ideal, pp, HI, pPb) with the following change:
* updating HCal response corrections restoring the energy scale in HB and HE after introduction of TimeSlew simulation (DIGI) + Method 2 (RECO).

Given that the Method 2 will be used in all reconstruction scenarios, this synchronises the conditions to the reconstruction setup. The OOT PU corrections in Run1 GT being different than Run2 is not an issue: they were consumed by Method 1 (while method 2 does not require any new condition input), so they are now deprecated. As soon as method 1 will be dismissed, we will remove them: so please keep us informed about this change.
