Subject: [PATCH] Made headings link to themselves.

Made each heading link to itself, by placing an <a> tag inside each
<h[1-6]> tag.

Also adds class="header" to each header, allowing for the CSS rule
    .header a { ...  }
to remove all styling from the inner links, allowing the outputed
document to look like before.
