Make menus manipulation easier for plugin developers 

* Add a wp_nav_menu_objects filter, which gets a sorted list of all menu node objects in the currently rendered menu
 * Add current, current_item_ancestor and current_item_parent boolean member variables to each menu node object, which are true when the item has the current-menu-item, current-menu-ancestor or current-menu-parent CSS class respectively
