Updates #25 - Support for Sitemaps!

YAY! I might have just added full support for Sitemaps, using the Google
XML Sitemaps plugin for
WordPress(http://www.arnebrachhold.de/redir/sitemap-home/). That feature
needs better testing of course, but it seems very promising so far.
Minor changes, including a credits page(not started on filling the
content yet though).
