Taylors Recs -- Episode One: The Sass Menace

Just a discussion starter. There will be more to come, but I thought we could go in small chunks.

^^ My code review face.
Why clear all of these? At the moment, I just dropped `ul` (because I needed it) and `ol` (for consistency). Drupal's admin-menu is a floated `ul`, so this broke that area. I was thinking, though, we'll run into other times where we probably need lists to float properly, or allow a floated image/figure in text content. This may also happen with these other header tags. What did this help you achieve?
