(IZPACK-923) used localized question title

Hello everybody,
this is a tiny change that avoid the unneeded fallback to the unlocalized title of the question dialog, since the localized title is available but not used. See IZPACK-923 for more Info.

I would like also to misuse this opportunity to encourage you to use find-bugs and the eclipse built-in warnings. They would have told you that the variable title is not used and you would have found the bug before someone finds it.

Best Regards
