508 issues, fixes resizing bug, minor enhancements to blog layout

This is a fairly small update but with some important things in it.
- We add the US Flag and "Official Website" banner to all the pages
- 508 issues related to the presentation of our team members, labels on forms
- Puts an edit this page link at the bottom of every page
- Resizes the text under team member names on smaller screens

This PR rolls those to production.
