* Use yarnpkg alias to run Yarn (facebook#1365)

There’s a common tool included in Hadoop that also has a `yarn` command,
which created issues for users who had Hadoop installed:
* facebook#1257
* facebook#1363

Yarn also installs the command under `yarnpkg` alias (added in
yarnpkg/yarn@cefa9a3)
so we can use `yarnpkg` instead of `yarn` to make it more reliable.

This has no effect on users who don't have Hadoop installed, but those
who have won't see errors from falsely detecting Hadoop Yarn as Yarn
the package manager, and they can now also install Yarn to make use of
our Yarn support without the Hadoop Yarn interfering.

Array.forEach is passed the following parameters:

currentValue
    The current element being processed in the array.
index
    The index of the current element being processed in the array.
array
- https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/forEach

console.log takes multiple arguments. We only want to print the first one, the actually message.

* webpack-dev-server patch for 'still-ok' success status (facebook#1377)

* Document Flow support (facebook#1384)

* Document Flow support

Projects created by Create React App use the `babel-preset-react` which includes
Flow babel plugins which introduces new syntax. This is important for users to know
as it causes what used to be syntax errors to be silently suppressed because they're
valid type annotations in Flow. For example if a user accidentally has `[foo: 'bar']`,
Babel will silently convert it to `[foo]`.

* Readme: Removes experimental from Jest snapshot (facebook#1453)

Per final comment in facebook#372

`Snapshot rendering should actually be pretty stable / useable after React 15.4.1.
See this post for more info.`

* eject: Additionally remove `react-scripts` from dependencies (facebook#1458)

ATM if react-scripts is (erroneously) declared in `dependencies` instead of `devDependencies` or isn't declared at all, the `eject` script will fail half-way. This change makes it more robust, react-scripts will be removed from either, if present.

* E2e jsdom fix (facebook#1470)

In the production build, ExtractTextPlugin is used to generate a separate CSS file instead of injecting style through JavaScript. This plugin does not work well by default with nested output structure. To fix it, we give it a relative publicPath pointing to the build folder.

* Make build exit with error code when interrupted (facebook#1496)

* Make build exit with error code when interrupted

This addresses issue facebook#1493.

Current behavior is that `npm run build` exits code 0 without creating a bundle when interrupted. This change makes the build script catch catchable interruptions and exit with the appropriate error code.

* Better error messages for kill signals

* Don't catch SIGINT

Ctrl+C should exit silently, and already produces a non-zero exit code when sent to the console while `npm run build` is running. Exit code 0 is produced if SIGINT is sent directly to the `node build.js` process, but this is unlikely to happen. A SIGINT handler in `build.js` will also be triggered by Ctrl+C in the console, potentially producing unnecessary noise.

* Style fix

* No changes needed to build.js

Problem is coming from the parent process, `react-scripts`
