Adds a Prepaid & Charge billing mode to carrier.account.mixin and overrides the stock.picking method that sets the shipping cost on sales orders after shipping. This modifies the behaviour of "invoicing policy" on delivery.carrier when a delivery billing mode is selected on the SO or picking.

Carrier Account Mixin.

|

This class provides functionality for handling carrier accounts within an order
|
|
system. It ensures that the correct carrier account is used based on the
|
|
delivery billing mode (collect, third party, prepaid). It also provides methods
|
|
to compute and validate carrier accounts according to the selected carrier and
|
|
partners involved in the order.
|
|
|
|
Most implementations should override the sender_id and recipient_id fields with
|
|
related fields that simply point to the res.partner record that is appropriate. For
|
|
example, the sender_id for a sales order would be company_id.partner_id and its
|
|
recipient_id would be partner_id.
