* Support top-level GitHub repo URLs

Adds support for top-level GitHub repo URLs, e.g.
https://github.com/username/my-cool-next-example.

This is already possible, but you have to enter "/tree/master" (or the
desired branch name) after the repo URL.

The change itself simply expands that URL to
https://github.com/username/cool-next-example/tree/$DEFAULT_BRANCH_NAME
where DEFAULT_BRANCH_NAME is the default branch configured for the repo
in GitHub.

It is any elements and not only meta or title because the children of next/head are generated in here: https://github.com/zeit/next.js/blob/8c899ee5e4cadc0a1cb47918613c1f6028b26314/packages/next/next-server/lib/head.tsx#L139
where React.cloneElement is called without the third parameter which is needed to clone the children as well (https://reactjs.org/docs/react-api.html#cloneelement).

This change updates the README of the `react-intl` example to show how to use
the FormattedHTMLMessage component from `react-intl` in Node environments when
using pre-v4 versions.

* Add dependencies used by compiled files

* Update utils.ts

* Add babel-types package

`next dev` was failing with:

```
Error: Cannot find module 'babel-types'
```

* Upgrade to the latest bs-platform

Also add the `babel-types` package to stop the `next dev` command from complaining.

* Remove extraneous babel-plugin-bucklescript dependency.

Seems the dependency has been deprecated, and it doesn't seem to be required
anyways.
