Add date choice for write-off on manual reconciliation

When we pay and reconcile an invoice, the date of payment is used as the write-off date, but when we reconcile manually with the wizard account/wizard/wizard_reconcile.py, the date for the write-off is the date of the day when we reconcile it, even if the payment was done a few weeks/months ago.

There should be a date field for the write-off when we manually reconcile entries.

It is possible to do that with these new lines of code. I also add code to get the most recent date of the account move lines which should be the payment date. This date can still be changed in the reconcile form, it is just an extra.
