Adding SubToMe buttons

Hey Brian,

I added 2 SubToMe buttons: one at the end of the posts, because well I think it's a good call to action if someone enjoyed what they read and one to the home because it's where people can quickly find more about you. For the home page I had to alter the CSS a little bit to that it's still looks like the other bullets (<li>), as well as link to the feed in the HTML's head section (because that's how discovery for feeds works...).
Let me know what you think. Sorry for the delays.
