Invoices created from sales orders now include the related sales order notes, helping customers and staff see important context directly on the invoice. When several sales orders are combined into one invoice, invoice lines are ordered more clearly so notes and products do not become confusingly mixed.

Sales Order notes were not passed in when generating the invoices.

     * [IMP] When generating an Invoice from several SO's the lines sequences
       were copied from the SO's. Because of that the resulting Invoice
       could have lines mixed-up between the different SO's which could
       be confusing, especially as notes are now passed in too.
