netconfig is not translated to Italian, German, Spanish, or French.
It is translated in the installer (TUI and GUI).
All of the other setup screens (with the exception of lokkit and
soundconfig) are translated as expected.
There aren't any translations for it; the installer screen isn't the
same thing (ditto for lokkit.)
For mr. i18n... :)
Because it isn't hosted on sources - I can move it if you request it.
Feel free to contribute translations, there's not much I can do about it (moving
it to sources would be A Pain).
