title: Open a website in crosswalk webview
body: <p>I'm building app with newest versions of cordova and crosswalk. When i launch the app, i want to open mywebsite in crosswalk webview instead of default browser or chrome.
     I'm trying to use:</p>
  
  <ol>
  <li><code>window.location.href="http://www.webpage.com"</code></li>
  <li><code>window.open('http://webpage.com', '_self');</code></li>
  </ol>
  
  <p>But they did not work. If i use them, the app asks me where i want to open my site in chrome or in default browser. I tried to use:</p>
  
  <ol>
  <li><code>navigator.app.loadUrl("http://google.com", {openExternal : true});</code></li>
  </ol>
  
  <p>But i've got a white screen in app.
     I don't want to use InAppBrowser, cuz it opens website in default webview, i wanna open website exactly in Crosswalk webview. Can someone help me to open website in crosswalk webview?</p>
