1) Add TClone arrays to store the raw scint TDC and ADC paddle and values

The arrays are  frPosTDCHits, frNegTDCHits,frPosADCHits and frNegADCHits
There are filled in THcScintillatorPlane:ProcessHits
2) Also modified THcScintillatorPlane::ProcessHits explicitly set variable
padnum=hit->fCounter and index=padnum-1 so the the TClone arrays for
scintillator variable set padnum=1,16 while the index=0-15
Want pdnum=1-16 because it is used in a hitogram fo counts versus
paddle number
3) Because of change to filling PaddleNumber in ProcessHits had
to modify THcScintillatorPlane::PulseHeightCorrection so the
index variable "j" is set to etPaddleNumber()-1 .
