Misc. fixes to ex2html.sh
Misc. fixes to ex2html.sh

* Remove unused code left over from PHP site.
* Update ex2html with current 'Developers' link. simple_header.html
  was updated, but ex2html.sh does not use that file so we have to
  update it as well.
* Instead of html formatting examples with perl/enscript, just link to
  the GitHub page. This is much easier to maintain than the old system
  of running the source code through multiple different
  pretty-printing scripts, and, especially for the longer examples, it
  is much less redundant information to weed through when browsing the
  examples on the web.
