cookies aren't shared in iOS

[podo-nuna]

There is an issue with not being able to set cookies on iOS. I tried to solve this problem and finally I found out that it can be resolved using the sharedCookiesEnabled={true} property in webView. Can you apply it to the next version?

This should already be doable as {...rest} is passed onto the WebView on this line.

So something like:

<RichEditor
  ref={this._myEditor}
  placeholder="My placeholder"
  sharedCookiesEnabled
  ...etc...
/>

should work I believe.
