Italian Translation

Issue Summary

Hi
I've made the italian translation for this module. Hope that this helps :D

I've also noticed that in the administration panel, the following strings aren't translated:

"IP address tracking
Track IP addresses
If checked the IP addresses of users will be logged. This may be a privacy issue for some people, but is very useful for discovering spammers on community sites.
Discard IP logs older than:
Older IP log entries will be automatically discarded. (Requires a correctly configured cron maintenance task.)"

So it might be that you forgot to add multilanguage support for them.

Thanks for your work!
