Bug 178297 [Dialogs] - remove required field color
There are still some dialogs using the (now deprecated) class FieldAssistColors. We shouldn't color the required fields anymore in these dialogs: NewFolderDialog CreateLinkedResourceGroup ResourceWorkingSetPage ContainerSelectionGroup ResourceAndContainerGroup

layout = new GridLayout();
        layout.numColumns = 2;

        nameGroup.setLayout(layout);
        nameGroup.setLayoutData(new GridData(GridData.HORIZONTAL_ALIGN_FILL
                | GridData.GRAB_HORIZONTAL));
        nameGroup.setFont(font);
        Label label = new Label(nameGroup, SWT.NONE);
        label.setText(resourceLabelString);
        label.setFont(font);
        
        resourceNameField = new Text(nameGroup, SWT.BORDER);
        resourceNameField.addListener(SWT.Modify, this);
        resourceNameField.addFocusListener(new FocusAdapter() {
    		public void focusLost(FocusEvent e) {
    			handleResourceNameFocusLostEvent();
    		}        	
        });

        resourceNameField.setLayoutData(data);
