* what is between, before, and after can be changed. The link itself will be
* HTML.
*
* This function is used internally by wp_list_bookmarks() and should not be
* used by themes.

* 'show_updated' - Default is 0 (integer). Will show the time of when the
* bookmark was last updated.
* 'show_description' - Default is 0 (integer). Whether to show the description
* of the bookmark.
* 'show_images' - Default is 1 (integer). Whether to show link image if
* available.
* 'show_name' - Default is 0 (integer). Whether to show link name if
* available.
* 'before' - Default is '<li>' (string). The html or text to prepend to each
* bookmarks.
* 'after' - Default is '</li>' (string). The html or text to append to each
* bookmarks.
* 'link_before' - Default is '' (string). The html or text to prepend to each
* bookmarks inside the <a> tag.
* 'link_after' - Default is '' (string). The html or text to append to each
* bookmarks inside the <a> tag.
* 'between' - Default is '\n' (string). The string for use in between the link,
* description, and image.
* 'show_rating' - Default is 0 (integer). Whether to show the link rating.
