This dev release switches to a different Prowl library, changes several function names, and supports Messaging 4.x, therefore backwards compatibility is broken!
Added prowl_user.module - This module provides integration with Drupal's user system, and allows one to associate a Prowl API key with each drupal user. Also provides a custom action for sending a prowl notification by username. (instead of having to enter in the API key each time)
This release adds configurable actions to send notifications to the admin user, or any user whose API key you know. This introduces a dependency on the token module.
