    Make computed value of border-width 0 if border-style none
    
    From the css docs at http://www.w3.org/TR/CSS2/box.html:
    
        8.5.1 Border width: 'border-top-width', 'border-right-width', 'border-bottom-width',
        'border-left-width', and 'border-width'
    
        Computed value:  	absolute length; '0' if the border style is 'none' or 'hidden'
