incorporating the ad code stuff

to-do: ad some theme options to enable the widget areas in the right
spots and make sure they're styled appropriately
move meta box stuff to post-meta.php instead of editor.php
add a meta box to allow authors to add a youtube video link to posts

Currently only used in the "top stories" homepage layout but we might
use this more widely later
create the lib directory and update file paths
create the /lib directory
Add ability for widget titles to be links
