Improve report name

I agree that we do not need a new method. Currently its easy to extend a report name. Here is an example:

    @classmethod
    def execute(cls, ids, data): 
        pool = Pool()
        Product = pool.get('product.product')
        result = super().execute(ids, data) 
        if len(ids) == 1:
            product, = Product.browse(ids)
            if product.name:
                result = result[:3] + (product.name,)
        return result

I remember having issues with zip files when the sequence contained the / character. And probably this is related to both clients.
