Update radio-shield-3.js
Update radio-shield-3.js

no longer adding the .h3 class to the label, adding .radio-shield-label, .fs22, .georgia instead. 
Hover and clicked states (not including the shield graphic) now controlled by the css rather than in the js, by targeting the .activeLabel class and using very specific selectors.
adding the css

styles added = form styles + ( purple & gold styles = hover + active
styles )
