Persistent bans

[CuriousMike56]

Currently, server bans are cleared when the server restarts. It would be nice if they were stored in a file, by username & IP.

To expand on this, there should also be banned vehicles and usernames. The server scripts can ban vehicles, but the server must be restarted for the changes to apply.

Hi.

RoRserver has persistent state AUTH_BANNED(32) based on token in authfile - this is checked first when connecting.

There are also IP-bans which are created by "!ban " command and aren't persisted. Nickname is recorded but not checked: https://github.com/RigsOfRods/ror-server/blob/17cc7b5a6922f4c32dcb7ea0753cbacafed4c401/source/server/sequencer.cpp#L219-L225

Draft

• Maintain "blacklist.json" containing existing ban-records: https://github.com/RigsOfRods/ror-server/blob/17cc7b5a6922f4c32dcb7ea0753cbacafed4c401/source/server/sequencer.h#L137-L143
• Add nick-blacklist by adding a "type {IP, NICK, BOTH}" field to the above struct.
• Vehicle bans: add "![un]blacklist " commands, create new struct similar to ban_t and persist it in "blacklist.json" as well.
• Vehicle bans: record { truckfile name/truck full name, GUID }, but those be easily faked, we may need to record node/beam/wheel/command/hydro counts, possibly with custom checksums - whatever data server has available.
