Added Detector Specific Dead Layer

Added functions in DetectionSystemGriffin to accommodate unique dead layers for each detector. I'm going to email Bill the suppressed GRIFFIN file as I added some code in there.

I also wrote a new command to control the new detector specific dead layer code. The command is 
/DetSys/det/addGriffinPositionConfig 7 16 0
where 7 is the detector number (1-16), 16 is the position in the array (1-16), and the last integer is forward (0) or back (1) configurations.

Enjoy.
