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

`server/chat-commands.js` is now a directory. It's been split into
`core`, `moderation`, and `admin`. `info` and `roomsettings` from
`chat-plugins` have also moved to `chat-commands`.
Some cleanup:
- Bot commands for inserting HTML into rooms like `/adduhtml` have been
moved from `info` into `admin`.
- `/a` has been renamed `/addline`, for clarity (and also moved from
`info` into `admin`).
- Room management commands like `/createroom` and `/roomintro` were
moved to `room-settings`
- `chat-commands/admin` has been TypeScripted
Global types are defined differently for `.ts` files than for `.js`
files, leading to some confusion for past refactors.
This commit defines them correctly.
I'm also considering making certain global types only available under
namespaces, but I don't want to do that to `User` or `Room`, so for
now, there are no changes there, besides putting streams in the
`Streams` namespace (so `WriteStream` is now `Streams.WriteStream`).
