ptMon-pltDAQ.sh: changes for neutrino, bug fixes

Development occured on my home computer and most of the changes
in this commit are changes related to that.

Also, some bugs were fixed.  After plots are created in the tmpDir,
they should be coppied to ouputDir, but this was incorrect and was
fixed.  Secondly, the gnuplot Titles used '@' char, but this is a
special char, so I changed it to "at".
Added ptMon-all wrapper script for PT Monitoring

ptMon-all.sh: a wrapper script that runs all the PT Monitoring scripts.
Now that this is operational, I am expecting to make more of these
ploting scripts, and this script will call them.  This script is
intended to be run by cron and it also mangages STDERR from the plotting
scripts.  It puts errors into a log file.  The itention is that the logs
will also be processed by the script that builds the web pages.

I also changed the name of the DAQ output files.
