Collection of small fixes

[mrkishi]

I've been opening too many little PRs and these would have to be another 7... Instead, let me know if any of these are undesirable and I'll rebase them out!

• Removed some files that slipped in and got committed when they shouldn't, 219dd13.

• Removed long unused (and broken!) .flowconfig file, 6034df7.

• Pinned @types/node: it was at v10, even though we support v8, 43f5680.

• Pointed the types field to declaration files, 616e1eb. Typescript expects it to be a file and doesn't treat it as an entrypoint for .d.ts files, instead resorting to normal module resolution:

• Moved the sub-packages stub creation to build as per @Conduitry's plead, 2695d76.

• Split tsconfig.json into multiple projects: compiler, runtime and test. Each of these have different libraries and environments, so we can be more selective in what typescript provides them, 29b5218.

• Forced git to use unix line endings since tests fail on Windows otherwise, see Test suite passes on Mac, fails on Windows #2817, a08576f.

👏 👏 👏

create-stubs.js has also been updated on master in the meantime. I think that change is reflected in whatever your corresponding mechanism is for that in this PR, but please make sure.

[mrkishi]

Yeah, the create-stubs is reflected, but I need to rebase either way!
