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.
Untested Updates

ptMon-all.sh:
  * Fixed a bug checking outputDir
  * slight change to logging redirections

ptMon-pltDAQ.sh:
  * Added time-stamps to show progress
High Load on neutrino + DAQ plot cycles

neutrino had a high load of >66 all day on Sunday.  I'm not sure if this is
normal or not.  In anycase, I don't want to exacerbate it, so I added a load
check to the DAQ plotting program.

I also refactored the DAQ plotting program to allow for different "cycles" or
plot groups/series.  The script checks a new parameter and can run different
sets of plots, rather than all the plots all the time.  This allows one to
run different sets of plots from ptMon-all or sparate cron jobs.

Also, ptMon-all accepts and passes on the "cycle" type.  It also runs both
sites' DAQ plots in parallel.
