[grisbi-user] Italian translation

[Giovanni]

Hi everybody users and developers, I'm using Grisbi since a month and I 
found it very useful for my purposes. An italian translation is available 
but still incomplete, and I will be glad to help this community. 
It is my very first time in contributing to a project. I have read the 
wiki, but I am in trouble doing some odd mistakes. Someone want to help me 
and explain step by step how to contribute?
