Stop Propagation

At the moment we decided to don't support this feature into the core of FastEventManager because there are a lot of implementation around this feature. This is an example, _(*6)

$eventManager = new EventManager();
$count = 0;
$eventManager->attach("post", function () use (&$count) {
    $count++;
}, 100);
$eventManager->attach("post", function () use (&$count) {
    throw new \Exception();
}, 110);
$eventManager->attach("post", function () use (&$count) {
    $count++;
}, 120);
try {
    $eventManager->trigger("/post/");
} catch (\Exception $exc) {
    // STOP!
}
