Add Italian translation

Hello @NSoiffer ,
this is Tommaso from VisionDept SRL., the italian distributor for Vispero / JAWS. We are interested in tackling the Italian for MathCAT, and are ready to start translating.
Regarding speech, I kindly ask you to set up the environment with the automatic translations, so we can start out.
As for Braille, we'd need a discussion on what code to choose: in italy, almost everyone nowadays uses the LAMBDA Math Code (Italian version). Do you happen to have any familiarity with that?

Thanks a lot, and ook forward to getting started with this.

Tommaso
