changed SHMS DC binning to be consistent with calibration. Changed 2ns/bin to 1ns/bin in drift time histos. (#145)

* -added the lines to read run number to the top of the script.

* -Modified SHMS DC DEF FILE to display drift times with binning scheme same as used in calib.
-Added the most up-to-date shms dc parameters obtained from the modified shms dc calib. script

* -set option to use per_wire tzero ON.

Modified DEF-files for new names for the Cherenkov and Aerogel

The calibration scripts work in a very specific way. First you have to change the
`wire_drift_times.h` to read the correct run. Then you have to change the
`pdc_plane_time_zero` in the parameter file to `1280`, since it is hardcoded.
Then you replay the run with these values and run the calibration. Then you
get the correct corrections to the time zero.
