[Gfoss] IT GUI translation improved for upcoming 1.4

Hi all.
We're happy to let people know that, thanks to the hard work of Maurizio Napolitano
and Flavio Rigolon, the Italian translation of the GUI has now been greatly improved,
and is now completed, so we're ready for the release of 1.4.
All the best.
