Italian files for ktouch

[Sebastian Gottfried]

Hello Luca,

> "Appunti di Informatica Libera" [1]. (translated: "Free Computer
> Science Notes".)
The lessons look good. They are mostly real text as I prefer it. I'll 
add them to next release. Thanks for your contribution!

Best regards,
Sebastian
