[tldoc] Announcement: Italian translation is here!

[Karl Berry]

    I also suggest these changes to include the now available Italian
    tlmgr/tldoc

Ok.

    Sorry if they are in plain diff, 

Not a problem.  (For the future, diff -c or diff -u is better.)

    PS. I don't have access to the repository. Should I post the .tex
    file here?

Yes please.

Can you translate the top-level README stuff too?  Much simpler :).
See readme-html.dir/readme.en.html and 
readme-txt.dir/README.EN.

Thanks,
Karl
