[5.0] Add invoiced date on make invoice in sale order

[Christophe CHAUVET]

I made a lot of invoice with the wizard "Make invoice" on sale order, this wizard ask if i want to group invoice per partner, but i can't put a spécific invoice date when the invoice was generated, i must reopen each invoice and add this date manually.

For ex, we are the 1 august, and the invoice must have invoice_date to 31 July, if the invoice date on invoice date is blank, it take the actual day when click on create, specialy if my delay is based on the last day of the month

I made a small patch to implement this, and it ran at one of my customers,
