Title: Allowed SaturdayDelivery option on national boxes

Checked with BPost employees. They confirmed it produces valid XML output that gets accepted in their testing environment and it is an option for every national delivery type. They only need to finish their stuff and deploy to production.

So just don't use this option. Yet.
