first steps to making emulator match unpacker output.

So far I've added the needed conversion scales to the CaloParams object (maybe not a good idea) and changed both jet algorithms to using the conversion code in legacyGtHelper.{cc,h}. Suggestions welcome.
Tau hw values now match gt.

Bonus: HI Tau algo now forbids forward taus
jet sorting is now done in the algo block itself, not in the finder or calibration.
pp Tau algo now using GT scales
tau and jet Et scales are now properly converted to physical values, etsums and egammas not done yet, eta still incorrect
EtSums should now be in GT scales.

Eta is not important for them
PhysicalEtAdder should be working with the GT coordinates now
Fix memory leak in EGamma algo
add some debug to PhysicalEtAdder
Merge branch 'l1t-devel-CMSSW_7_1_0_pre7' of github.com:cms-l1t-offline/cmssw into devel
fix further memory leaks
add inheriting class of CaloParams which holds scales
Move all Stage1 classes to use new CaloParamsStage1 class instead of CaloParams class
Merge pull request #14 from richard-cms/match_gt

I didn't see any complaints and this doesn't break anything outright, so I'm merging to make sure future work happens on top of this.
