message type

PHPTemplate displays all messages in a 'Status' section, effectively dropping the drupal_set_message parameter $type. Drupal core makes use of a type 'error' in a few circumstances, and contributed modules use other types. taxonomy_context uses 'term'

Adding a DIV around the message to denote the type allows phptemplate to act like xtemplate, and for type of 'error' , the result is that drupal.css colourises the message.
