Take into account all the remaining remarks of Frederic Clementi dated May 30:
- see multi-currency amounts in the wizard to add transaction lines
- add help msg on bank payment lines
* IMP: prevent deleting a move-line that is linked to a payment order line
* FIX: better filtering of move lines already included in open payment order
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
- add wizard of selection of move lines to pay
