title: How to set a user agent and use a proxy?
body: <p>The documents read as follows: </p>
  
  <blockquote>
    <p>user-agent</p>
    
    <p>since v0.3.7</p>
    
    <p>(string) Override the User-Agent header in HTTP requests made from the application. 
    The following placeholders are available:</p>
    
    <p>%name: replaced by the name field in the manifest.
       %ver: replaced by the version field in the manifest, if available.
       %nwver: replaced by the version of node-webkit.
       %webkit_ver: replaced by the version of WebKit engine.
       %osinfo: replaced by the OS and CPU information you would see in browser's user agent string.</p>
  </blockquote>
  
  <p>Can someone give me an example of how this implemented? eg. Current user agent:</p>
  
  <pre><code>Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_3) AppleWebKit/537.36 ...
  </code></pre>
  
  <p>Say I want to make it:</p>
  
  <pre><code>Chrome/5.0 (Windows NT) Chrome/35.0.1916 ...
  </code></pre>
  
  <p>Also, I'd like to use a proxy... is that possible within node-webkit? </p>
