pg_resetxlog and pgscripts italian translation

Hi,

These are the first translations of the pg_resetxlog.pot and pgscripts.pot =
files. The "it" option is missing in both the nls.mk files so it must be ad=
ded. I will now start to work also on cleaning up and adjusting the psql.po=
t file i posted 2 days ago.

Best Regards,
