Load routes under console environment too.

Prior to this update, application and plugin routes were not available from the console environment. The filter that loads the routes in bootstrap/action.php, applies to lithium\action\Dispatcher only. The filter logic for loading routes should also be applied to lithium\console\Dispatcher, so that Router related capabilities such as URL generation is possible from the console. 

One use case for this, is generating email notifications from the console as a CRON job, where application URLs need to be generated within the email.
