[trunk] [sale/purchase] : picking order date is not the same as the sale/purchase order date

When I create a sale order with an order date different from the current date, this date is not kept in the stock picking. Indeed the date in the stock picking is the current date.
To fix this bug you should just add the line :
=== modified file 'sale/sale.py'
