Mail only invoicing

In the profiles of the companies to be able to specify an email only for invoicing. So that when sending the invoice, this email is sent by default and not the reservation email.

It is usual that the travel agencies send us the reservation requests by an email of the type reservas@...... and that the invoices are received in an email of the type facturacion@.........

We are realizing that sometimes by mistake we have sent the invoice automatically to the wrong email and now we are balancing invoices. I think this new feature would help a lot.
