 It's helpful to have a visual indicator when a top level menu item
 contains a hidden drop down menu.

 This patch adds a filter to wp_nav_menu_objects in order to add the class
 "has-children" to top level menu items that contain children.  This allows
 us to style it with psuedo element, similar to how the menu-toggle is
 styled for smaller screens.

 The filter I used was posted by @chipbennet on the WordPress Theme
 Reviewers List. The same functionality could also be achieved by a Custom
 Nav Walker (see http://wptheming.com/2013/03/drop-down-menu-indicator/),
 but Chip's solution seemed more straightforward.

 Neither method works unless a menu has actually been set.
