[FIX+IMP] account_payment_order:

* FIX: Bug #353 crash when selecting a payment mode that has a variable link to a bank account
* FIX: Add 'post_move' option on account.payment.mode with default True, to keep the previous behavior
* IMP: Explicit error when bank account is missing on bank journal
* IMP: Add field default_date_prefered on payment mode.
