[Customer Invoice] Automatically send the invoice generated from a template

[Thatoo]

Feature Request

Currently, template invoices allow us to automatically create, validate and generate PDF with a predefined periodicity. But we still need to send the invoice to the customer by e-mail manually.

Use case

Use template invoice.
Once an invoice is generated from a template, you need to send it by e-mail

Suggested implementation

On the template invoice object, add the following fields :

• Automatically send by e-mail (yes / no) : mention to explain it will auto validate these invoices
• E-mail model to use (dropdown with models available for invoices)

The sender is the user connected to run the planned task (so it must have proper e-mail setup) and the recipient are the contacts linked to the invoice with BILLING role or the e-mail on the thirdparty card. An error e-mail must be send to the sender if no e-mail is available to send the invoice.

An other way, probably easier, integrate https://github.com/bugness-chl/sendrecurringinvoicebymail into Dolibarr's core.
