4182	Add ability to return list for wp_list_categories..	profdeadmeat	rob1n	"Simply:
  The function outputs directly to the page it does not allow any function to use the output.

Impact:
  Plugins and templates which used the deprecated list_cats can not use the replacement.

Fix:

  Change: 
      echo apply_filters('list_cats', $output);

  To: 
      $output = apply_filters('list_cats', $output);
        if ( $echo ) echo $output;
      return $output;"	enhancement	closed	normal	2.3	Template	2.1.3	normal	fixed	has-patch
