A little more padding on the homepage

This is just a silly PR, but I thought you might want it anyway. It adds equal padding to the top and bottom of `<body>`, so things are vertically, visually pleasing :)

I hadn't heard of TasteJS until about 20 minutes ago, and I can't help but be intrigued. Is there anything you guys need help with? Styling, writing (JS or copy), or general grunt work all sounds fun to me!
