Nebula Anti-Cheat (NAC)

A basic anti-cheat for Luanti. Note that this is not a replacement for the built-in anti-cheat, but rather an addition to it. This is intended for simple mini-game servers rather than heavily modded survival servers. The defaults are stricter on purpose so you don't miss any important checks, so just disable anything that falsely triggers for your server, or file an issue in the repository. If you are testing the anti-cheat for accuracy, make sure to turn on the verbose setting and give yourself the alert privilege (and be aware that while some checks may occasionally false flag, if it doesn't reach the point of triggering a setback, punishment, or alert in non-verbose mode, then it isn't an actual issue).

Players with the nebula_anticheat_alert privilege can see anti-cheat alerts. Note that this isn't required, since punishment is automatic.
