Convert 'team' page back to 'about' page.

Adds an 'about' paragraph to top of the page, mostly taken from FAQ page
(wordsmithed both of 'em a bit to promote profile thing a bit more). Changes name
and link back to 'about.'  Makes a few tidiness changes to page (new j pic, spacing, etc).
Update Jason and Heather's descriptions only enough to remove old Heather title
and add cofounder for both of us.

Fixes #49.
