Vendorize React. This is required at this time because we need to modify it to work with QtWebKit.

The patch to do that has been submitted upstream; if accepted, we can un-vendorize again.

# `react-dom`
This package serves as the entry point of the DOM-related rendering paths. It is intended to be paired with the isomorphic React, which will be shipped as `react` to npm.
## Installation
```sh
npm install react react-dom
```
## Usage
### In the browser
```js
var React = require('react');
var ReactDOM = require('react-dom');
class MyComponent extends React.Component {
render() {
return <div>Hello World</div>;
}
}
ReactDOM.render(<MyComponent />, node);
```
### On the server
```js
var React = require('react');
var ReactDOMServer = require('react-dom/server');
class MyComponent extends React.Component {
render() {
return <div>Hello World</div>;
}
}
ReactDOMServer.renderToString(<MyComponent />);
```
## API
### `react-dom`
- `findDOMNode`
- `render`
- `unmountComponentAtNode`
### `react-dom/server`
- `renderToString`
- `renderToStaticMarkup`

/**
* Summary of `ReactBrowserEventEmitter` event handling:
*
* - Top-level delegation is used to trap most native browser events. This
* may only occur in the main thread and is the responsibility of
* ReactEventListener, which is injected and can therefore support pluggable
* event sources. This is the only work that occurs in the main thread.
*
* - We normalize and de-duplicate events to account for browser quirks. This
* may be done in the worker thread.
*
* - Forward these native events (with the associated top-level type used to
* trap it) to `EventPluginHub`, which in turn will ask plugins if they want
* to extract any synthetic events.
*
* - The `EventPluginHub` will then process each event by annotating them with
* "dispatches", a sequence of listeners and IDs that care about that event.
*
* - The `EventPluginHub` then dispatches the events.
