This just configures flow to be checked and fixes our existing Flow typed files. Possible enhancements: Export .js.flow declarations from the build. Unclear whether this will be a supported workflow in the future or not, so let's wait on that. We should fail builds and CI on Flow errors. Ideally we should lint for Flow style guides (like no space before colon).
