Change name of the @Observes Reception attribute to "notified"

As of the CDI 1.0 specification, the name of the Reception attribute on @Observes is "receive". The patch release of the API (SP1) changes the name to "notifyObserver", so a change is already being considered. Therefore, I'd like to suggest a better name that would read more fluently. That name is "notified".

Let us compare the three cases:

1. @Observes(receive = IF_EXISTS)
2. @Observes(notifyObserver = IF_EXISTS)
3. @Observes(notified = IF_EXISTS)

Of the three, notifyObserver breaks the flow of the sentence the most. On the other hand, notified reads nicely, including with the TransactionPhase attribute included:

@Observes(notified = IF_EXISTS, during = TransactionPhase.AFTER_SUCCESS)
