title: How to change WebView settings from QML
body: <p>I'm using a simple <code>WebView</code> in my QML file. </p>
  
  <pre><code>WebView {
      anchors.fill: parent
      url: "file:///android_asset/example.html"
  }
  </code></pre>
  
  <p>The problem is, that I'm getting an error about <code>access-control-allow-origin</code> is <code>null</code>. I found a fix for this <a href="https://stackoverflow.com/questions/42224717/web-view-dont-load-web-image">here</a>, which is using WebView <code>settings</code> property. It seems to be accessible from c++, but I haven't found any way of using this property from qml. So how can I use <code>WebView</code> settings from QML to get rid of the error? I'm using Qt 5.10.</p>
