Add parameter 'isgrid' to plotting of arcs.
Smithgrid and polar plots could not discern between xgridwidth and
xbrushwidth. This is now available, similar to straight line plotting.
Tested also for PS and SVG.

Add code in graf.c to merge connected lines with the same slope before
plotting. This speeds output and reduces file size when the vector
length is much larger than the number of pixels. It should help with
Feature Request #58 :
"Graph plotting under windows redraw very slow and hard to work with",
but is not a full fix.

With the ngspice gnuplot command, enable x/y contour plots for 2d Cider save file data. Usage: gnuplot <file> xycontour <expr>. xycontour is a new flag which is ignored if the plot data is not from 2d Cider. For contours, only a single plotarg <expr> is allowed. With <expr1> vs <expr2>, only <expr1> is plotted and <expr2> is ignored.

Add variable 'plainplot' to allow plotting without
function support, but with node names incl chatacters like + - /.
Flag to command 'plot' is renamed to plainplot.

If new parameter 'plain' is added to the 'plot' command,
all expression handling is skipped, vectors are plotting as is.
This allows nodes names with vectors like v(+vs) or /out
to be plotted without need resorting to double quotes.

Don't add copied scale vector as new vector, but as new scale vector,

When plotting arrays of curves, plot lines only in the direction
of (in absolute terms) growing x values.
Example: MOS output characteristics.
In the rare case of plotting versus varying x directions
(e.g. example memristor.sp), one has to add the flag
'retraceplot' to the plot command.
