[Xfce-i18n] Italian translation

[Vincenzo Reale]

Hi all,
my name is Vincenzo Reale and I'd like to contribute to the XFCE Italian 
translation.
Long time Italian KDE translator, I'm also involved in different 
Transifex hosted projects as coordinator or translator and other 
translation platforms.
I recently installed Manjaro XFCE on my parents' PCs and found some 
typos and untranslated strings in the current translation.
I'll be glad to give my contribute improving it.

Thank you in advance,
Vincenzo
