Clearfix

Hey Jordan,

It looks like the problem with your menu was just that some pages didn't have the clearfix class on them. So, since we're floating the menu items to the left, the sizing got a little weird.

I changed the five files that had `<ul class="nav">` to be `<ul class="nav clearfix">`. If you click the filed changed tab up above, you can see those changes. There are also some other changes where my editor automatically removed extra spaces or tabs.

If you merge this change, it should be all set.
