LibDraw+LibHTML: Make link colors themeable

Browse source 
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.
