Merge lp:~therp-nl/banking-addons/6.1-aggregate_payments into lp:banking-addons/6.1

[Stefan Rijnhart (Opener)]

From the module description that this branch adds:

This module allows for aggregating payments for various creditors and making them payable to a single partner. This is practiced in certain purchasing consortia.

After collection of the payable invoices on a payment order of type 'Aggregate payment', the move lines in the payment order are reconciled by a move on a transit account, the total amount of which is then transferred onto the designated partner's account payable (upon confirmation of the aggregate payment order).

The payment order wizard then proceeds to create a new payment order of a user chosen payment mode with only the aggregate move line in it.

Notes:
- The dependency on account_direct_debit is completely artificial. It only needs the two fields that it adds to the payment mode. This calls for a refactoring which actually has already been carried out for 7.0. I would prefer to leave 6.1 as it is to be honest.
- I am not sure about the English terminology 'Aggregate payment' and 'Transit move & account'. Any suggestions are welcome.

180. By Stefan Rijnhart (Opener) on 2013-06-13

[FIX] License and expected revision number, uneven spacing in xml

[Holger Brunn (Therp) (hbrunn)]

Just a small thing:

#700 can reference be False here?

review: Approve (code review)

[Stefan Rijnhart (Opener) (stefan-opener)]

No, should not occur as it is a required field on the payment order that has its own sequence in the default configuration.
