Add QCD BTV fragments for RunIIFall14GS pure pythia8

I add here all the fragments assigned to BTV for the pythia8 production (with the exception of the QCD inclusive bins already present that were used for the recent RECODEBUG production for 72X digi-reco): i.e. MuEnriched pThat >20 GeV, ptmu>15 GeV; MuEnriched 12 ptHat bins ptmu>5 GeV; bcToE, eT>10 GeV (this value was not specified in the spreadsheet but it is the one used in previous requests); QCD inclusive (added extra 3 pThat bins).

Cross sections and filter efficiencies have been computed with 100k events.
