Site update

I have updated this site to use Leonardo v0.5. I was running a hacked version of 0.3 before, so there could be breakages. The only hack I've done to this one is to redirect the RSS feed I added to Leonardo to a SmartFeed at feedburner.com, which is apparently a good way to keep track of what people do when they read the site via a feed. I'd appreciate email (pt at ptsefton.com) if you notice any problems.
