WIP: Attach the Worker events to the CakePHP Event System

[cleptric]

This is WIP for implementing #7 I started with the Worker events. Queue is missing, but it's only one event. Also, tests are missing, but I want to discuss this first.

Now you can do sth. like:

use Cake\Event\EventManager;

EventManager::instance()->on('Queue.Worker.job.success', function ($event, $job) {
    debug($job->data['job']);
});
