META: New RSS feeds

I've introduced a new feature here on the blog -- RSS feeds for each category, so if you only want to subscribe to certain kinds of posts without being bothered by the rest, you can. In the sidebar on the right you'll see the category list like always, but now each entry has a little RSS logo next to it. Clicking on that will take you to the feed for just that category.

For instance, you can subscribe to just the HeroMachine 3 updates, or just the Daily Random Panel, or whatever else tickles your fancy, without having to sift through Bad Costumes or inane Movie Reviews and whatnot.
