- Translations
- Added support for the CP949 Korean Codec.
- [138140] The whole Qt source compiles with the QT_NO_CAST_FROM_ASCII
  and QT_NO_CAST_TO_ASCII defines and therefore is more robust when
  using codecs.

- Changed dialogs to respond much better to the LanguageChange event.
  (i.e. run time translation now works much better.)

      waits for all slots to be called before continuing.

      signatures (struct, class, and enum).
    * Optimize emitting signals that do not have anything connected to them.
