Global Exception Handling

I would recommend putting the try catch block also around the controller instantiation, as then you can also throw exceptions from eg an auth lib. Finally, if the method_exists() fails, I would have called show_error().

Also, I suggest moving this to the Feature Requests section. But I don't think it will be supported until CI goes PHP 5 fully.
