Title: Can now set errorsKey for en error response

This change allows you to set a `key` to the `withErrors` method when sending back a response. This is a small change to help a user if he has multiple errors on one page. So instead of duplicating the `response` method in our `FormRequest` class when we need to change the key we just set the `$errorsKey` property.
