Add "Link", "ActiveLink" and "VisitedLink" colors to the system theme definition, and implement support for them in LibHTML. Note that <body link="foo" alink="bar" vlink="baz"> takes precedence over the system colors. Author style also takes precedence, since we only fetch the system color in case the CSS color is -libhtml-link.
