Cache labels for "Next>" or "Finish" button in wxWizard so that their translations stay consistent throughout wizard's lifetime: previously, this button could use a label in a different language if the currently used translations have changed since the wizard creation, as this label was recreated on every page change, unlike the other labels which were only translated once in the very beginning.
