Cumulative updates to HipPy scripting, TwoBodyDecay, Alignment/OfflineValidation and MuonAnalysis/MuscleFit macros

[cmsbuild]

• HipPy scripts have been improved
• HipPy contains preliminary Y(1S) and Z constraints
• TwoBodyDecay package has been revived, was giving token errors before
• Y(1S)->mumu validation in Alignment/OfflineValidation, support from MuonAnalysis/MomentumScaleCalibration
• These changes have already been used in producing the supermed EOY16 tracker alignment candidate currently being used and some of its validations
• The PR is probably one day too late for 900pre5, but we would like to have it included for the earliest possible release.
