Title: Adding documentation for product input attributes

I discovered some additional product attributes that can be supplied to create. I added a new section to the product api page that duplicates the Product Attributes section with changes to the product_family_id and the additions of require_billing_address, request_billing_addresss, and taxable.

I haven't tested return_url or return_params as we don't use those.
