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.

IObservableValue emfTTipObs = EMFObservables.observeValue(me,
				ApplicationPackage.Literals.MITEM__TOOLTIP);
		if (widget instanceof Control) {
			ISWTObservableValue uiTTipObs = SWTObservables
					.observeTooltipText((Control) widget);
			dbc.bindValue(uiTTipObs, emfTTipObs, null, null);
		} else if (widget instanceof org.eclipse.swt.widgets.Item
				&& !(widget instanceof MenuItem)) {
			ISWTObservableValue uiTTipObs = SWTObservables
					.observeTooltipText(widget);
			dbc.bindValue(uiTTipObs, emfTTipObs, null, null);
		}
		
		((EObject) me).eAdapters().add(new AdapterImpl() {
			@Override

				MPart<?> sm = (MPart<?>) msg.getNotifier();

						.getFeature())) {
					Widget widget = (Widget) sm.getWidget();
					if (widget instanceof org.eclipse.swt.widgets.Item) {
						org.eclipse.swt.widgets.Item item = (org.eclipse.swt.widgets.Item) widget;
