seperated middle name into own field - was causing PDS validation to fail when combined with first name

re-configured to run in production as fastcgi process not starman (can't find statics without own domain name); required full path to wkhtmltopdf for apache; replaced {data} with write() setter for session(); removed superfluous style.css from pdf layout (just needed p style declaration); some web pages needed request.uri_base to run as fastcgi

fixed session storage and retrieval failure in Role::PDS - needed to use read() method to access and {data} key to store; completed all functions - version ready for testing with HILIS4
