	 * Initializes the component: creates the BlobberPlugin and the BlobberWorker objects.
	 * <p>
	 * Raises an alarm (FF="Monitoring", FM="MonitorArchiver", FC="2") if initialization fails.
	 * This makes sense because the blobber runs as an autostart component, and the manager being 
	 * the client that activates this blobber would not know the alarm details. 
	 * @TODO: Shouldn't we use a FM specific to this blobber instance?
