configuration.md was missing most options added over the last few years. Add the controller, host and instance options that weren't listed, mark the internal ones, note the validation rule under each field that has one, and fix entries that had gone stale: the tls defaults, the proxy_stream_timeout name, game port assignment from host.factorio_port_range, the three sync list modes, and the player_online_autosave_slots heading.
Plugin options live in the plugin READMEs, so add the missing ones for inventory_sync, player_auth and subspace_storage there. config-system.md gets the field definition properties it didn't list yet.

The role of a slave as a host for Factorio servers is not well reflected
in its name and has caused confusion among users. Rename slave to host
to better reflect its role as a host of Factorio servers.
The role of the master server as the party controlling every part of the
cluster is not well reflected in its name and has caused confusion among
users on several occasions. Rename master to controller to better
reflects its role.
Simplify the the way markdown files are formatted to make them easier to
author without editors that do auto line breaking, and make the diffs
from them simpler to read.
Add authentication plugin that does a simple challenge response protocol
to verify that the player trying to log in is who they claim to be. The
process goes as follows:
1. A player code is generated for a player that wants to log in and is
displayed in-game.
2. The player code is input into the web interface and the master
generates a verification code as a challenge back along with a token.
3. The player inputs the verification code in-game and is logged in to
the web interface in doing so.
To do the actual login the web interface polls a verify endpoint every 2
seconds until the code has either been verified or expired. The
challenge comes from being unable to control the verification code and
having to input it as a player logging into one of the servers in order
to login.
Some additional steps are taken in order to increase the difficulty for
an attacker to subvert the challenge:
- The login process must be started from in-game.
- Generated codes are only valid for a limited timespan which is
configurable and 2 minutes by default.
- The verification code comes with a token that only works with one
player code and verification code combo and must be provided to pass
validation.
