The sim no longer uses any global variables, so this can and should be
removed.
`server/global-variables` has also been cleaned up, since I'm working
on this.
We're skipping two major typescript-eslint versions, so there are a
bunch of changes here, including:
- it's catching a lot of things it didn't catch in the past, for
reasons unclear to me
- no-unused-vars has to be explicitly disabled in global-types now
- a lot of `ts-ignore`s were never necessary and have been fixed
- Crashlogger can now handle being thrown things that aren't errors.
This has never been a problem in the past, but to satisfy TypeScript
we might as well not die in a fire on the off chance someone tries to
`throw null` or something.
This is mostly just a follow up to #6342.
`prefer-optional-chaining` was turned on and fixed in every location it
complained in. The transformed function [0] looks expensive from a
glance but from skimming through the replaced sites it doesn't appear
to be ran in any important place, so it should be OK.
The linter improvements are:
- Increase linter performance
- Make `full-lint` and `lint` write to different caches so we
avoid overwriting their caches since they're different configs
- Change husky's hook to `npm run lint` so as to write to the
same cache
- Remove `@typescript-eslint/eslint-plugin-tslint` which is
essentially a wrapper to TSLint because the rules aren't worth
running another linter
- Convert `.eslintrc.json` and `.eslintrc-syntax.json` to two spaces
rather than four tabs to respect PS' `.editorconfig`
- Rename `fulllint` to `full-lint` to ease spelling it
