Some code cleanup

Hey man - saw your project and it's looking great! Noticed a couple unclosed html tags so I thought I'd fix them up for you, and also cleaned up a few other bits and pieces.

You might want to start using a consistent line indenting format in your editor. Which style to use is a religious debate, but the rails style guide says to use two spaces for everything instead of tabs, so that's what I stick with.

Whitespace changes can make things confusing in git because it looks like something has changed, but it's just the layout.
