[NFR] Implement method \Phalcon\Forms\Element::setMessage()

[iforp]

It would be very useful methods:
\Phalcon\Forms\Element::setMessage(string $message)
and
\Phalcon\Forms\Form::setMessage(string $elementName, string $message)

[iforp]

Or may be this method should be named appendMessage

Error messages should be attached to the form elements, not the form itself:
#542 (comment)

The current implementation is not logical and has an artificial restriction:
https://github.com/phalcon/cphalcon/blob/1.1.0/ext/forms/element.c#L662

Form should refer to the elements to get the error messages, but not vice versa.
