debugbar code appended to exported file

[chauchakching]

The debugbar code is appended to exported file as well...
It should check the response output format before appending the debugbar code.

On my Plugin.php, I've put this code inside the public function boot() method:

Event::listen('backend.page.beforeDisplay', function($controller, $action, $params){
       if( $action == 'download' ){
           \Debugbar::disable();
       }
});

Advise above looks good
