A handful of changes, mostly stylistic:
* Removed the commented out `The People` and `Our Partners` pane. No need for this to sit in comment - use it or lose it.
* Set a consistent min-height on the featurette wells under the hero unit, making the boxes look a little less wonky.
* Did some spring cleaning in the stylesheets. Also, added `.well-featurette` styles.
* Tidy up and add comments to functions, add theme screenshot, and make some totally unnecessary changes to style.css.
* More style changes: base fonts on px then just convert to em from there. Add some color to the navbar brand element, which was invisible. Undo the unnecessary changes to style.css.
