When an "import" is started, the first thing displayed is the "localization" dialog box. It would be helpful to have a "Cancel Import" button if the user found their way here unexpectedly.
Add a 'cancel' button and events to the GedcomLocalization class.
Add a 'gedcom localization cancel button click' handler to MainWindow.xaml ("GedcomLocalizationControl"). Add the code to mainwindow.xaml.cs (see gedcomlocalizationcontrol_continuebuttonclick and other such handlers for the code to execute).
