- Use the new [@react.component] decorator for all of the react
  components and bindings.
- Use the new react hook integrations for the counter component.
- Add a `npm run dev:reason` and `npm run dev:next` commands to make
  running the build processes in separate terminals easier.  I didn't
  update the README because I'm unsure if this is something that would
  be desired.
- upgrade to reason react 0.7.0
- upgrade to react and react-dom 16.8.6
- upgrade to bs-platform 5.0.3
- upgrade to @babel/core 7.4.3

* feat(fela-example): replace old API with new ones

instead of letter apollo rely on a global variable, we pass it explicitly to the HttpLink constructor.

This adds a test to the custom-server suite to make sure we don't regress on this

if `&amp=1` is used to point to the `amphtml` version of a page it get's escaped causing it to become `&amp=1` this fixes it to stay as `&amp=1`

* Add x-powered-by

* Remove ampEnabled type

Just a minor typo fix: `Github` -> `GitHub`.

Not sure when it was introduced, but on the latest Next v8.0.4, there's no descriptive name attached to the component returns from `withRouter`.

This makes it harder to debug and write test cases for components wrapped by `withRouter`.
