Nix Support

[Cyberboss]

🆑
Added Nix support.
Added the --bootstrap parameter to the host watchdog, which will cause it to look for TGS binaries in ~/.tgstation-server/lib instead of its local directory. This also causes it to read and save which TGS version should be used/was in use in ~/.tgstation-server/bootstrap.json
Fixed issues with engine installation jobs if the EngineInstallComplete script errored.
Fixed incomplete engine installations lingering if the EngineInstallComplete script errored.
The EngineInstallFail event will no longer run if the EngineInstallComplete script errored.
Fixed an issue where aborting a zip file upload for a TGS update would prevent the server from updating without a restart.
Added support for global EventScripts directories.
Released artifacts are now attested.
/🆑

🆑 Configuration
Added General:AdditionalEventScriptsDirectories array which can be used to specify EventScript directories that are used by all instances.
