The "Produced by Haddock" footer was overlapping the page's body when printing.
This patch hides the footer with a css media rule.

Any extensions that are not enabled by a used language (Haskell2010
&c) will be shown. Furthermore, any implicitly enabled are also going
to be shown. While we could eliminate this either by using the GHC API
or a dirty hack, I opted not to: if a user doesn't want the implied
flags to show, they are recommended to use enable extensions more
carefully or individually. Perhaps this will encourage users to not
enable the most powerful flags needlessly. Enabled with show-extensions.

The Xhtml backend has special markup for that, Hoogle and LaTeX reuse
what we have for DocEmphasis.

	don't generate an empty li for absent style menu in links area
	update css for Classic and Snappy to handle:
		dl lists
		links in package header and in declarations
		floating of links and info block in package and module headers

  make whole .caption be the target
  improve javascript for class toggling
  have plus/minus images come from .css, not img tags

- add CSS for lists 
- renderToString now uses showHtml since prettyHtml messes up <pre> sections

    switch to using the xhtml package

    copied Html.hs to Xhtml.hs
        and split into sub-modules under Haddock/Backends/Xhtml
        and detabify

    moved footer into div, got ready for iface change
    headers converted to semantic markup
    contents in semantic markup
    summary as semantic markup
    description in semantic markup, info block in header fixed

    factored out rendering so during debug it can be readable
        (see renderToString)
