Demozoo production or graphic submission: FIX title/releaser duplication

Often a record on DZ will have redundant information that gets duplicated on the importing into DF2. For example, a record with the Title of "Edge Of Honor WHQ BBS (14)" and as is categorized as an "Advert for Edge Of Honor WHQ". Both these data points get imported and are unnecessary, so if a Title contains the content found in Advert for, the Title should probably be ignored during importing.
