Bug 60714 Call Hierarchy: display search scope in view title
Call Hierarchy should display the current search scope in the view title, like the Search View does. E.g.: Members calling 'updateView()' - in Workspace Calls from 'updateView()' - in Working Set: my projects

List actions = new ArrayList(SearchUtil.LRU_WORKINGSET_LIST_SIZE + 4);
		addAction(actions, fSearchScopeWorkspaceAction);
		addAction(actions, fSearchScopeProjectAction);
		addAction(actions, fSearchScopeHierarchyAction);
		addAction(actions, fSelectWorkingSetAction);
		
		Iterator iter= SearchUtil.getLRUWorkingSets().sortedIterator();
		while (iter.hasNext()) {
			IWorkingSet[] workingSets= (IWorkingSet[])iter.next();
			String description = SearchUtil.toString(workingSets);
			SearchScopeWorkingSetAction workingSetAction = new SearchScopeWorkingSetAction(this, workingSets, description);
			
			if (isSelectedWorkingSet(workingSets)) {
				workingSetAction.setChecked(true);
			}
			
			actions.add(workingSetAction);
		}
		
		Action[] result = (Action[]) actions.toArray(new Action[actions.size()]);
		
		ensureExactlyOneCheckedAction(result);
		return result;

		int checked = getCheckedActionCount(result);
