Restore display of profile name in application title when non-default profile used. Fix Mac-specific problem with application menu: on Mac systems there's a global menu, so deriving sub-windows from QMainWindow can mess up the application window. Sub-windows should be derived from QWidget instead of QMainWindow to avoid this. Changed MailEditorWindow appropriately (hopefully, needs a Mac tester now).
