Updated HTML version of demo scripts now on SourceForge

[Ethan A M. <merritt@u.washington.edu>]

I wrote a perl script to auto-generate a web page for each gnuplot demo 
script.  The perl script itself is now in the CVS tree as demo/webify.pl
I used it to create web pages for almost all of the current demos.
They are on
	http://gnuplot.sourceforge.net/demo/

There were some problems with the pm3d.dem run, and the
vector.dem run didn't work at all.
