[sane-devel] [backends] Italian translation update

[Vincenzo Reale]

Hi,
that's my first message on the list and I would like to take the 
opportunity to greet all the participants.
My name's Vincenzo Reale and I'm a long time translator in several FOSS 
projects.
I found that the latest Italian translation revision is really old, so I 
decided to refresh it.
I would ask you which is the right way to provide an updated revision.

Thank you in advance,
Vincenzo
