Add invoice pdf in billing email

My monthly task of opening the URL, saving the invoice HTML as a pdf and uploading that to our expense system could be very simplified if I could get the invoice attached as a pdf to the billing email. If that was the case I could set up an automatic rule to forward the billing email to our expense system - making me a lot happier!

Hi, @Oskr - The ability to add attachments automatically to outgoing email is coming soon - stay tuned!
