Fixed a bug with person ID #'s around the site, and whether or not they have a leading 0. Book annotations properly insert the 0s if necessary, and the person_detail_db view no longer cares if IDs have leading 0s.
Some changes to the CSS and display for person_detail pages.
Changed the people page to use the database, and added the ability to filter the results by role.
Removed unecessary views and template.
