[ghost]

Because of this, themes can be applied too.

Description

Add class to support the :before CSS part. This will allow theming, and shows the new OC radio buttons.

Suggestion

Replace e.g. all
input[type="radio"].radio:checked + label:before
by
input[type="radio"]:checked + label:before
so these edits aren't needed. It's redundant anyway, since all vanilla theming (default OC theming) should be applied to all radio buttons and check boxes.

Fine by me for now, but I'm not sure everyone will think about setting the "radio" class on all new radio elements.

Which is why

input[type="radio"].radio:checked + label:before

should be replaced in you big styles.css or input.css by

input[type="radio"]:checked + label:before

And so on.
