title: Checking network connection throughout app (titanium)
body: <p>I am able to do this ok in single controller files:</p>
  
  <pre><code>Ti.Network.addEventListener('change', function(e) {
      networkIsOnline = e.online;
      networkType = e.networkType;
  
      alert(networkIsOnline);
  });
  </code></pre>
  
  <p>However, what is the best way to have this event listener, listen globally - so that I don't have to keep on copying and pasting that code?</p>
  
  <p>Cheers.</p>
