Complete copyright notices for web interface; change footer to link to them. The original copyright notice found in the footer was not accurate as it included only one of the many copyright holders in this project. This change creates an "about" page, which currently contains just the copyright and license information. It links to repository for additional potential copyright holders not listed on the about page. Unlisted contributors are mentioned in template comments. Html links for Kallithea is fixed and we link to Conservancy. Display of version information in the footer is improved.
