Create About Team page

[davepagurek]

To get this to work:

• Change people.json to be included in Mustache template data by reading it in Gruntfile.js and setting globals to it
• Get people to fill in missing content
• Figure out where we want this - as a new page, but linked to in the footer? as a button to switch the footer to show the info there? as a button to show the info in the main page header?
