Added a "mud" label feed

When I set up my blog to use FeedBurner, apparently that clobbers the ability of the viewer to choose what they want the feed of my blog they would subscribe to, to contain. All they can get is the "FeedBurner" complete feed. In order to work around this, I have added a specific FeedBurner feed for the "mud" labelled posts. This is linked in the right-hand side of my blog, so go and grab it if you don't want to listen to the rest of my witterings on other subjects.
