Bug 198971 [CommonNavigator] Provide extension schema for setting help ID
I haven't been able to find a way to set the help ID for a view using the common resource navigator. It seems that having schema support for this would be the best way to handle this.

	public void createPartControl(Composite aParent) {
		final PerformanceStats stats= PerformanceStats.getStats(PERF_CREATE_PART_CONTROL, this);
		stats.startRun();
		commonViewer = createCommonViewer(aParent);	
		commonViewer.setCommonNavigator(this);
		
		try {
			commonViewer.getControl().setRedraw(false);
			
	        INavigatorFilterService filterService = commonViewer
					.getNavigatorContentService().getFilterService();
			ViewerFilter[] visibleFilters = filterService.getVisibleFilters(true);
			for (int i = 0; i < visibleFilters.length; i++) {
				commonViewer.addFilter(visibleFilters[i]);
			}
	
			commonViewer.setSorter(new CommonViewerSorter());
