Adapt to updated UT channel ID class and geometry

(1) Changes based on new UT geometry & channelID (2) stripID shifted. Now start from 0 instead of 1

Work with DDDB!79, SIMCOND!143, LHCb!2995 (merged), Lbcom!550 (merged), Moore!785 (merged), Allen!865 (merged), PRConfig!230, Detector!181 (merged)
