Movable Type 4.0 upgrade

I’ve just upgraded the site to the new, improved version of Movable Type (the blogging platform I use.) This should make improve the blog in the long run, but in the short term it basically just means that I’m back to using one of the default layouts. This will (maybe) change over time.
The only important thing that’s missing is the links to the feeds from the main page; the two afeeds (Atom and RSS) are both still there and working, but you can’t get to them unless you know they’re there.
