User-Agent header not getting set with 'source' prop in Android Webviews

[mtostenson]

With the recent addition of the 'source' prop to Android webviews, developers can provide a custom set of headers to the webview when making a request. However, in Android, the User-Agent header gets set through the webview settings and cannot be applied the same way as the rest of the headers.

WebView has undocumented 'userAgent' property, you can try use it like this:

<WebView
    userAgent='MyApp'
    style={{flex:1}}
    source={{uri:this.state.url}}/>

works only for android.

@gentlee, appears to work for IOS as well on v0.29.0. Thanks!
