title: Always show zoom controls in WebView
body: <p>Is there any way to always show zoom controls in webview?
  I found this: <a href="https://stackoverflow.com/questions/920741/always-show-zoom-controls-on-a-mapview">Always show zoom controls on a MapView</a>
  but that's for the mapview.
  I want them to always be visible.</p>
  
  <pre><code>    super.onCreate(savedInstanceState);
      super.loadUrl("file:///android_asset/www/index.html");
      WebSettings ws = super.appView.getSettings();
      ws.setSupportZoom(true);
      ws.setBuiltInZoomControls(true);
  </code></pre>
