/**
 * Outputs a list of all links, listed by category, using the settings in
 * $wpdb->linkcategories and output it as a nested HTML unordered list.
 * Differences to the WP function: Outputs h3 instead of h2, outputs the count
 * of links behind the category name.
 * 
 * @param order Defines how to sort the link categories. Possible values are
 * 'name' and 'id'. Optional, defaults to 'name'. Use '_name' or '_id' to
 * reverse the sort direction.
 * @param cats A list of categories. If not provided, all link categories will
 * be retrieved from the database, omitting empty categories.
 * @return The overall count of displayed links.

/**
 * Gets the links associated with the given category.

 * @param category The category to use. If no category is supplied, the
 * function gets links for all categories.
 * @param between String to output between elements within the list element
 * (between link and notes, notes and update time).
 * @param show_images True to show link images (if defined), false to not show
 * images.
 * @param orderby The order to output the links, e.g. 'id', 'name', 'url',
 * 'description', or 'rating'. Or maybe owner. If you start the name with an
 * underscore, the order will be reversed. You can also specify 'rand' as the
 * order which will return links in a random order.
 * @param show_notes Whether to show the notes.
 * @param limit Limit to X links. If not specified, all links are shown.
 * @param echo Whether to echo the results, or return them instead.
 * @return The html to output if echo is true.
