Modified hodoscope and scintillatorplane code for hodo calibration

Temporarily set THcHodoscope.cxx so that only the first three planes are used to calculate the focal
plane time and beta.
In THcHodoscope , Modified format for writing out the dump file used in hodo calibration.
Add cosmicflag to THcScintillatorPLane so the corrected time is done right for cosmics.
Modified hc_hodo_calib/tofcal.f so that it uses detector 10 as the reference
and that it writes out better defualts for parameters in there are not enough events for a PMT.
