[NFR] Add proper support to \Phalcon\Form for Radio button

[scrnjakovic]

The way radio buttons work in Phalcon, as far as I got them, is:
Form initialization

$this->add(new Radio('published'));

View

{{ form.render('published', ['value':'Y'])  }}
{{ form.render('published', ['value':'N'])  }}

Hi @scrnjakovic,

I think that's kind of a hack since, it's rendering de same component twice with different values.

i.e. you can't set two different labels.

Gender:
(x) Male ( ) Female.

You can't use:

Gender: <br>
{{ form.render('gender', ['value' : 'M']) }}: {{ form.label('gender') }} 
{{ form.render('gender', ['value' : 'F']) }}: {{ form.label('gender') }}

Well, sort of. It is hacky when it comes to labels, whereas it is quite valid when it comes to the input itself. I do generally agree with you, but that wouldn't solve the issue. I wish I had more time to dedicate to this discussion, but I would like to ask you to write an example code to render a radio and labels for the following use cases:

1. Gender: (x) Male ( ) Female
2. (x) I agree ( ) I do not agree (note missing third label)
   and in the process you will see what I meant.

Radios and checkboxes are conceptually completely different than other input controls and I think that the design of Phalcon\Forms\Element, a base class of all elements, does not support that. It goes beyond ID/Name.

P.S. This is how I use it, and we have the same particular case:

{% set genderElement = form.get('gender') %}

{{ form.label('gender', ['for': '']) }} // Gender label

{% do genderElement.setLabel('Male') %}
{{ form.render('gender', ['id': 'male', 'value': 'M']) }}
{{ form.label('gender', ['for': 'male']) }}

{% do genderElement.setLabel('Female') %}
{{ form.render('gender', ['id': 'female', 'value': 'F']) }}
{{ form.label('gender', ['for': 'female']) }}

stripped HTML and attributes for simplicity

Closing in favor of phalcon/cphalcon#13855. Will revisit if the community votes for it, or in later versions.
