The array keys are event names and the value can be:

- An array composed of the method name to call and the priority
- An array of arrays composed of the method names to call and respective priorities, or 0 if unset
For instance:
- array('eventName' => 'methodName')
- array('eventName' => array('methodName', $priority))
- array('eventName' => array(array('methodName1', $priority), array('methodName2')))
