I know that I can get the default description of a Task with:
$this->description;
//or
$this->getDescription();
But how can I get the description if it got changed on creation:
craft()->tasks->createTask('Mailer', $new_description);
Adding it as an attribute doesn't seem "right" to me:
craft()->tasks->createTask('Mailer', $new_description, array('description' => $new_description));
