Added chat feature!

Hey guys!

So I added a "chat" feature to the side bar, if you notice. Since I haven't updated this thing in a while, visitor rates have dropped pretty significantly so you'll be lucky if you're not the only one in the chat room. Anyway, if you leave messages there, I will eventually see em, so leave ideas for content! Lemme know what you think about the layout. Thanks guys!
