Patch a sent invoice

Patch fields on a SENT invoice. Supports updating the purchase order number, customer billing address, memo, reference, and due date. Setting a due date records it as manually chosen and clears the invoice's stored payment terms, so it will not be recomputed from them later. The due date can be moved but not cleared: sending an explicit null for it is rejected.
