doc: styles for man page, which suit with the mercurial website

designed loosely based on:
http://mercurial.selenic.com/css/styles.css

with some modifications by intention:

 * visited links are colored differently
 * no fixed size
 * works without typeface.js

we keep most styles, which is from docutils, untouched.

tested with:

 * MSIE 6.0 on Windows
 * Firefox 3.5 on Linux
