Translator for the Italian sbn.it

I have added the translator for the Italian National Library System (Sistema bibliotecario nazionale). Following the recommendations in http://www.zotero.org/support/dev/how_to_write_a_zotero_translator_plusplus  I created two files: one for the search results page and one for the individual entry page. 
PS: I also create a BibTex translator tailor made to work with Biblatex and Biber
