HTML Bug Fixes & Compliance

- Fixed buggy HTML
- Attempted to comply with W3C HTML5 specification more
Implemented "About" Webpage

Implemented temporary "About" page's HTML and integrated with existing
code (About and Main servlets)
Fixed Registration Servlet Bug

Registration Servlet checked for a nonexistent "nocaptcha" parameter
from form, probably propagated from making Contact Us page captcha
optional. Removed offending code and included failsafe registration
rejection in catch block.
Contact Us (Servlet Failsafe & Data Viewer Bug)

- Included feedback rejection in catch block of Contact Us servlet
(similar to that which was done in Registration servlet)
- Fixed bug in Questions/Clarifications Data Viewer originating from
prior change to user authentication scheme (removal of usernames)
