sass/desktop.scss, css/desktop.css
Added css to allow for columns of lists in the dropdown menu as per marketing template

js/menu-columns.js
Added javascript to automatically creat columns in the dropdowns longer than 7 items
note: This can be overriden by adding custom columns via the special_menu_items module.

template.php
_uw_menu_alter: disabled the unsetting of children to allow columns in menu.
 jtw84: We should prolly discuss whether there's a better way to do this.

page.tpl.php
Wrap both $primary_nav and $page[dropdowns] in div.collaps and nav#access tags
Hide div#navbar-menu if neither $primary_nav nor $page[dropdowns] is used.

uw.info
Added reference to the js/menu-columns.js
