Migration scripts for account_payment_order must be triggered only on OpenUpgrade migration
from v8 to v9, so the version should be 9.0.1.0.0, as there has been other intermediate
versions.
This commit also removes obsolete migrations scripts.
Improvements include:
- full re-organisation of modules and big re-organisation of the code
- simplification of the code related to the fact that support for direct debit is now in t
he base module, not added by an optional module account_direct_debit (module was removed)
- new design of the wizard to select move lines to pay
- support for non-SEPA file transfer-
- support for German direct debit SEPA files (fixes bug #129)
- remove workflow of payment.order
This port to v9 is not finished... there is still a lot of work:
- finish the code of account_payment_order/wizard/account_payment_line_create.py
- port account_banking_payment_transfer and integrate it inside account_payment_order
- fix bugs
- clean-up code, remove dead code
- test in several complex scenarios
