Add a blog

We should add the long-planned blog to our site. The first entry can just be a link to DANKTECH 001 and the µnandfs technical report, so as not to procrastinate on generating blog content =]. The blog ought be reachable from the front page via a link; by this I mean either the most recent post, or a list of posts, or both. All blog pages ought reach back to the front page.
