title: How to handle progress events with GeckoFX
body: <p>I want to be able to display the page loading status (i.e. waiting for server, downloading page, etc) using GeckoFX.</p>
  
  <p>The Navigating event is perfect for letting me know when a page has started loading, but I need to know when it is finished loading.</p>
  
  <p>I know the GeckoWebBrowser class has an IsBusy property. I could run a timer and to check this and update the status but this is just a hack at best.</p>
  
  <p>I'm not trying to create a full blown browser here, just some basics. Can anyone nudge me in the right direction?</p>
