Add "-D N" and "-N" options.  Debug and nice.

Now I can leave in some debug printouts.
-N is good for cronjobs

+The -D N set the debug level to N and outputs with more verbosity.  0
+is the default, quiet except for all ERRORs and some WARNINGs.  9 is
+painfully verbose.
+
+The -N option will force ntpviz to run "nice"ly.  This is appropriate
+when you run ntpvizz as a cron job.

 The plot options choose what graph is generated; invoke only one.  By
 default, the GNUPLOT for the graph is reported; with -g you get the
 rendered PNG.
