Adds two "sidebars" to the header.  You can drag and drop widgets into them just like any other sidebar from your WP dashboard.  You can change the Hook to move the "sidebars" somewhere else on the page.  For example, change 'thesis_hook_header' to 'thesis_hook_after_html' and your new sidebars will show up there.  Style using CSS to change their layout.
