Description: [enhancement] Better link styles for the included
documentation
Details:

I have problem with the look of the links in the included html documentation
($PG_INSTALL_DIR/doc/html/stylesheet.css). Now they have the following style
defined:

A:link { color: #000066; }
A:visited { color: #000099; }
A:active { color: #FF0000; }

And such styled unvisited links look a lot like the non-styled visited links
and vice versa. It would be better if they were left unstyled or with a
style that does not resembles the default style for links but in reverse.
