[Koha] bugs in 2.2.0RC1

Hi, 3 bugs have been found (and fixed) in Koha 2.2.0RC1 : * import in reservoir : bug that makes title & isbn being empty instead of being correctly found. * OPAC : it was possible to reserve books that were "notforloan" * Circulation : no warning when a reserve was made on a book that you try to issue to someone else. I'll release a 2.2.0RC1b today or next day (with some french translation improvements probably) -- Paul POULAIN Consultant indépendant en logiciels libres responsable francophone de koha (SIGB libre http://www.koha-fr.org)
