Don't delete nav menu items when the user that owns them is deleted.

Browse Source 
* Introduce delete_with_user flag to register_post_type
* Set delete_with_user to false for the nav_menu_item post type
* Set it to true for all other core post types
* If delete_with_user is not set, fallback to post_type_supports('author')

Props nacin
