The Docker configuration now tries to do a better job of letting people

know that the Review Board image is for a backend server, and is not

meant to be accessed directly. This is done through repeated use of

"frontend" vs. "backend" terminology and a big note when creating the

image.
The docs list newer example versions of Review Board versions, so it

doesn't appear too ancient.
The Nginx configuration has been updated based on the latest version of

what we auto-generate when creating a site. The docs and the

auto-generated configuration also have some updates based on best

practices we've used in our own servers.

Built the docs and read through them, looking for errors.
Tested the Nginx configuration locally.
