Converted nearly every page to PHP. Moved content to ‘content’ folder. All pages contain code, not content.

Pending issues:

1. Determine whether modified date is the date of the footer file or the date of the file that calls it.
2. All CSS and included files have absolute http:// references to graphics and style sheets. Determine whether this is best practices.
3. The CGI counter now counts hits on all pages, not individual pages. The PHP include must work differently than the SSI include. All pages are now being counted in the CGI-bin file under one file.
4. Confirm that all pages have same type reference to CSS and include files.
