[Html-widget] Radio button group

[Carl Franks]

I've commited (v 5037) the changes to the RadioGroup element.
http://dev.catalystframework.org/repos/Catalyst/trunk/HTML-Widget

There's slight classname differences from my earlier description, the
main ones are documented in a new CSS pod section in RadioGroup.pm

The OP's request for horizontal styling is also documented there.

Unlike other elements, which are only wrapped in a 'label' if there's
a label set,
the RadioGroup is currently always wrapped in a 'fieldset', regardless
of whether the label or legend is set.
Is this desired behaviour?

Here's an example of the output...

<form id="widget" method="post">
<fieldset class="widget_fieldset">
  <fieldset class="radiogroup_fieldset" id="widget_foo">
    <span class="radiogroup_label" id="widget_foo_label">my label
    </span>
    <span class="radiogroup">
      <label for="widget_foo_1" id="widget_foo_1_label">
        <input class="radio" id="widget_foo_1" name="foo" type="radio"
value="0" />false
      </label>
      <label for="widget_foo_2" id="widget_foo_2_label">
        <input class="radio" id="widget_foo_2" name="foo" type="radio"
value="1" />true
      </label>
    </span>
  </fieldset>
</fieldset>
</form>
