Add after validation hook

[mikaelpopowicz]

Add the Laravel validation after hook.

Implement the afterValidate(Validator $validator, array $inputs) method in FormValidator child class.

Example :

use Illuminate\Contracts\Validation\Validator;

class ChildForm extends FormValidator
{
    ...

    protected function afterValidate(Validator $validator, array $inputs)
    {
        if ($this->somethingElseIsInvalid()) {
            $validator->errors()->add('field', 'Something is wrong with this field!');
        }
    }
}
