Update the AUTHORS content and LICENSE date.
Review Request #11124 — Created Aug. 5, 2020 and submitted — Latest diff uploaded
The AUTHORS file now gives a little more detail as to who is maintaining
Django Evolution and fielding questions (us), and adds a section about
the original maintainers (partly taken from the original FAQ content
when they handed the project over). This is partly to ensure people
don't unnecessarily bother them, and come to us instead, but also just
to add some history to the project.
The license has been updated for the current year.
Ran spell check.
