title: External scripts not working in Windows Phone App 8.1
body: <p>I've added a WebView into my project. If I navigate to the html file that contains external javascript files they don't work. Bit if I write the javascript code hardcoded into the html file it works properly. </p>
  
  <p>Here is the html portion:</p>
  
  <pre><code>&lt;!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"&gt;
  &lt;html lang="en" xmlns="http://www.w3.org/1999/xhtml"&gt;
  &lt;head&gt;
      &lt;meta charset="utf-8" /&gt;
      &lt;title&gt;&lt;/title&gt;
      &lt;script type="text/javascript" src="testjs.js"&gt;&lt;/script&gt;
  &lt;/head&gt;
  &lt;body&gt;
      &lt;div id="abcd"&gt;&lt;/div&gt;
      &lt;br/&gt;
      hello! this is a simple html block. 
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>Here is the javascript portion:</p>
  
  <pre><code>document.getElementById("abcd").innerHTML = "New text!";
  </code></pre>
  
  <p>When I open the webview it shows </p>
  
  <p><code>hello! this is a simple html block.</code>, </p>
  
  <p>but if the javascript code worked it would show </p>
  
  <p><code>New Test!
  hello! this is a simple html block.</code></p>
  
  <p>Here is the folder structure:</p>
