Email Subscription added

I wasn't sure if you were getting updates via email when the blog was being updated, so I added a FeedBurner Email Subscription button that should email you any time there is an update to the blog. This way you don't have to randomly check up on the blog to see if there have been updates and you can input whatever email address you check most often. 

UPDATED: I updated the Feedburner link. I don't think it was working before. I either had the wrong feed link, or didn't put the post feed on the blog (or because Google just took over feedburner, maybe there was some downtime.) I'm  not sure. Email subscriptions should be working now.
