Missing validator message should contain validator name.

In case of:

$form->addText('stars', 'Stars')
	->setRequired('Please select stars.')
	->addRule(Form::NUMERIC)
	->addRule(Form::MIN, null, 0)
	->addRule(Form::MAX, null, 5);

It is not clear from the original message in which validation rule the validation message is missing. The form can be built dynamically from multiple places. This feature adds the name of the validation rule that requires the message.

Thank you.

$rule->validator can be also callable array or Closure.

@dg FIxed, validator will be inserted only in case of string.
