Italian translation error causing bug in theme custom options

The Italian translation of this element:

Overrides the WordPress %1sfront page option%2s

needs to be fixed in order to access the input fields for the front page custom title and subtitle.

Due to the wrong translation, clicking on these fields leads to the front page option page, without any chance to edit the fields content.

The correct translation (changed with Poedit and tested) is:

Sovrascrivi le opzioni della %1spagina di copertina%2s di WordPresscopertina%2s di WordPress
