Bug 382887 CustomControlExample CTabFolder should have setTopRight
CTabFolder tab in CustomControlExample should have a means of testing setTopRight (to a toolbar, for example). Also, allow the top right style (SWT.RIGHT, SWT.FILL, and SWT.RIGHT | SWT.WRAP) to be selected when calling setTopRight().
