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
bundles/org.eclipse.ui.ide/src/org/eclipse/ui/internal/ide/misc/ContainerSelectionGroup.java
boolean allowNewContainerName, String message,
			boolean showClosedProjects, int heightHint, int widthHint) {
		super(parent, SWT.NONE);
		this.listener = listener;
		this.allowNewContainerName = allowNewContainerName;
		this.showClosedProjects = showClosedProjects;
		if (message != null) {
			createContents(message, heightHint, widthHint);
		} else if (allowNewContainerName) {
			createContents(DEFAULT_MSG_NEW_ALLOWED, heightHint, widthHint);
		} else {
			createContents(DEFAULT_MSG_SELECT_ONLY, heightHint, widthHint);
		}
