New Rules module - better messaging (cover drupal_set_messages() options using Rules)

I need the ability to purge all existing messages (drupal_set_message), and to send messages in different type other than the original action provided by Rules.

Attached to the proper issue (I hope) is the new module - "Better Rules Message".

Do you think this module should be by its own, or should it be merged into the Rules module ?

Comments are welcome,
