Thanks for submitting some updates to the i18n file! I've got a request for you though; in PR #15, some changes were suggested to the i18n file as well. Since I don't speak any Italian, I was a bit hesitant to merge these changes without checking with someone else, and I never really put in the time to look for someone to check. Since you've also submitted the original i18n file, would you be willing to have a look at those changes as well, and let me know which of those changes look good?

I think @Mannivu PR fixes mainly indentation/tabulation problems, the only real change (L232) is "es." instead of "e.g." that is correct. For me it's ok to merge #15 before this one but I don't know if I need to rebase/edit my branch to accomodate the new it.js.

I don't any problem to cancel my PR (I see that it has a conflict which I didn't see two years ago). My fix can be added to @valepert's PR since it was a minor fix.
