- Adds Global: Null Contextual filter for:
/about/people, /about/people/group

*/about/people/group/wrong_argument will not 404,
/about/people/group/wrong_argument/second_wrong_argument will 404

- Expand/collapse for contacts no longer trigger if text is selected anywhere on the page.
-<a> tag for the name of the individual links to the person page, but cannot be followed by a user.

Added a check to see if a table existed before updating. It was causing the update hooks to fail on single-page.
