Bug 283442 [UI] Refactor the rendering class names
In order to bring the model closer to the way in which we talk about it we should re-factor it to remove references to 'factory'. For now the re-factoring will to replace 'PartRenderer' with 'PartRenderingEngine' and to replace '<xxx>Factory' with '<xxx>Renderer'. Post 0.9 we expect to change these again but this will make the initial story clearer.

private final List partFactories = new ArrayList();
	
	public static final String SERVICE_NAME = PartRenderer.class.getName();
	
	
	public static final String FACTORY = "partFactory"; 
	
	private AdapterImpl visibilityListener = new AdapterImpl() {
		@Override
		public void notifyChanged(Notification msg) {
			if (ApplicationPackage.Literals.MPART__VISIBLE.equals(msg.getFeature())) {
				MPart<?> changedPart = (MPart<?>) msg.getNotifier();
				
				MPart<?> parent = changedPart.getParent();
