Improve plot comparison scripts.
* compare_plot_demos.m: pass toolkits{} to html_compare_plot_demos.
Give instructions for toolkit matlab. Fix whitespace issue.
* dump_demos.m: fix typo in default dir. Consistently use dump_plot_demos.m
for main worker script. Create diary and error messages for inclusion in
html page. Set random seed for better comparison.
* html_plot_demos_template.html: Allow variable toolkits (removed hard-coded
gnuplot, matlab, fltk sequence). Fix some whitespace issues.
* html_compare_plot_demos.m: Rewrite docstring. The instructions are no longer
needed because compare_plot_demos handles them. Add "toolkits" and
column_width param. Dynamically add toolkits in html, add diary.log link.
