PURPOSE
=======
The field auto_confirm is complicated to understand for common users. Furthermore, on of its options is only useful for authorize module.
SPECIFICATION
=============
Remove the auto_confirm field. The destinies of its options are the following:
- none: Simply disappear.
- authorize: Become capture_manually. It has nothing to do with the auto_confirm field has it's related to the autorize module (And could be extended to other payment acquirers too).
- confirm_so: Remove it. Will be automatic, and we will always validate the sales order and generate the accounting entries on acquirer validation.
- generate_and_pay_invoice: Is linked to the journal_id. The field journal_id is always set and we will use it to validate the sales order and generate the accounting entries on acquirer validation.
Bonus: website_sale: Allow to create/validate invoice automatically on `Mark as Paid`
Indeed as transfer transactions are always pending and independant of
any callback, it is not necessary to see credentials, auto confirmation
settings and error / cancel / done messages.
