2b2bba9ff3 Cleaned up some option-parsing logic 
$options{y2} and $options{extracmds} now default to [], so I never need to check
for defined $options{y2}.

This patch also changes some

 foreach()
 {
   dosomething();
 }

blocks into

 dosomething() foreach();

74e95d8e6f If using --timefmt then --xlen MUST have an integer argument 
I use strftime() and strptime() to deal with xlen in the timefmt case, and those
functions only work with integers

ffd19b9b87 --hardcopy now handles piped output 
If we tell gnuplot to plot to a file whose name starts with '|', gnuplot writes

99369d1542 y2-axis curves no longer have a thicker line by default 
This was causing an issue where gnuplot would complain if a points-only
--curvestyle was plotted on the y2 axis. This is because --linewidth makes no
sense for a points-only curve

d76f163be4 even simpler data storage 
The data for each curve is now stored as one big string that has ALL the data;
this string is easily sent to gnuplot at once. There's also a bit of attached
meta-data to allow streaming --xlen culling to work

70b7c98124 better handling of non-timer-based replots 
Previously I was ALWAYS replotting when triggered, ALWAYS replotting on a timer
and NEVER replotting on domain rollover with --monotonic.

I now have logic to do the right thing in all these cases. I now replot on
domain rollover, unless it's happening too quickly.

a41a64457f --legend and --curvestyle now use ' ' as a separator instead of '='. 
For example to set a legend for curve 'data' to 'datalegend' I now do
 --legend data datalegend

The previous syntax that used = produced hashes internally, which disregarded
the order of the given options. This resulted in arbitrarily ordered curves.
