Fix up images on homepage; #789

I fixed this by wrapping the three SQL query result sets in a generator
that creates a new ORM-based Participant object. Then we use the
get_img_src method on that object, which is the same one we use on
profile pages.
Bump version to 7.3.20
Bump version to 7.3.20-dev
Use user profile pic in OpenGraph card

This is a better than using a generic Gittip logo at all times.
