Subject: [PATCH 1/2] The following two features were added to the
 [sitemap_pages]-shortcode:  - only_subpages (default is false) If true, only
 subpages of the current page appear in the list  - sort_column (default is
 menu_order) Defines how the entries are sorted. wp_list_pages() got a list of
 possible arguments:    Comma-separated list of column names to sort the pages
 by. Accepts 'post_author', 'post_date', 'post_title', 'post_name',
 'post_modified', 'post_modified_gmt', 'menu_order', 'post_parent', 'ID',
 'rand', or 'comment_count'.    I think menu_order is the best of these.
 Before the posts where just sorted like they were placed in the database. Now
 the WordPress menuorder is taken into account.
