- Changed the way status messages are printed as per Kristjan's suggestion:
  http://drupal.org/files/issues/error_messages_list.png (issue #9138).

  drupal_set_message() has been changed to group message by type and a
  helper function, theme_status_message(), is added to display the messages.
  Chameleon and Xtemplate have been updated to use this new function.

- Updated CHANGELOG.txt.
