#296 Underline even visited links on hover

[Ernst de Haan]

Currently, visited links in the generated specdocs are not underlined when hovered over. This is due to a minor error in the specdocs CSS file. Just remove the:

a:visited { text-underline: none; }

from the CSS file.

Note that I've already fixed this in the XINS branch at github: http://github.com/znerd/xins/blob/master/src/css/specdocs/style.css
