Document: User permissions

In short, there are two types of users:

A "server user" -- someone added to the server from the CLI with ./feoblog add
A "known user" -- someone followed by a "server user"

A FeoBlog server does two main things:

store posts by "server users" and serve them
collect (i.e.: store) posts by "known users" so that they can be used to show "server user"'s feeds.

So as a result, both "server" and "known" users effectively get to post to a server.

However, if a "known user" follows someone (who is not already a server/known user on the server) they are not granted either user status.
