Merged l1t-devel-CMSSW_7_1_0_pre6 from repository cms-l1t-offline
Fixed a bug L62 Stage2TowerCompressAlgorithmFirmwareImp1.cc, it wasn't filling the hadronic pre compression towers. Also updated L1TCaloAnalyzer.cc to make many more histograms and turnon curves, including comparisons with l1extra and gen collections
