Adding an option for overriding the Kobo firmware behaviour when a book is replaced. The defualt behaviour is for the book to be removed from the internal database and then treated as a new book. This means the reading status is lost. But, the KoboTouch driver has always overriden this behaviour and to allow the reading status to be kept. The option is to override the firmware behaviour and defaults to on to keep the existing driver behaviour. Kobo has released new firmware. The only change is to bump the firmware and database versions.
