[RFR] Refactoring of direct debit to pull less dependencies.
Result of a sprint with Akexis de Lattre in a corridor at Fosdem 2014.
In a nutshell, this MP moves the hooks that are necessary for account_direct_debit from account_banking_payment to account_banking_payment_export, resulting in a leaner dependency graph [1].
account_banking_payment (and thus account_banking core) is therefore not necessary anymore for doing direct debit. account_banking_payment can now be seen as providing two essential functions: 1/ adding the notion of transfer account on payment modes (marking the invoices paid as soon as the payment order is sent) 2/ bridging with the bank statement reconciliation features of account_banking core
IMO, the next step in the refactoring process would be to move 1/ to a stand-alone module.
Other things in this branch: - removing auto_install=True that we found unnecessary and potentially risky - demo data by Alexis - a trivial bug fix - setting noupdate=1 for the SEPA payment mode types - allow payment of customer refunds lp:1275478
