Switch to Babel 7

Merged Administrator requested to merge github/fork/clemmy/2.0-beta into next

Created by: clemmy

Babel 7 has a lot of new goodies, including JSX fragments. This PR is an attempt to make a pre-release for users to try out Babel 7 with CRA.

Things I'm still trying to mesh out/blocked on:

  • Needed to disable pre-commit hook that runs prettier because it doesn't support JSX fragments, and wouldn't let me commit
  • Need to disable UglifyJsPlugin to make npm run build in react-error-overlay work, can't figure out why
  • Need to add old configuration back into babel-preset-react-app, currently it's overwritten with babel-preset-react
  • Address this PR?
  • Do I need to do anything with Lerna in this PR?
  • Need to re-enable https://github.com/airbnb/babel-plugin-dynamic-import-node. It might be fine to just put it in, but it'll download all the babel 6.x dependencies.
  • Tests are failing. Babel-jest works with Babel 7.x, but jest-runtime depends on Babel 6.x. What's the solution here?
