title: Catch all exception handler in global.cs
body: <p>What i would like to do is catch any exception that hasn't been handled in the web application then send the user to a screen saying something like</p>
  
  <p>"Were sorry this has crashed" </p>
  
  <p>And at the same time send the exception to our ticketing systems. </p>
  
  <p>I am assuming I need to put it in the the global.cs somewhere just not sure where?</p>
