Commit 8a6e859 wrongly introduced this new field when adding the new
`payment_authorize` module.
As 8.0 is a [stable version](http://git.io/vfACM), no data model change
is allowed.
We convert this field to a `fields.dummy` in case someone installed (or
update) this module with this fields to ensure the view still applied
and is not broken.
- added a call to _migrate_paypal_account in the payment_paypal data that
does the migration from company.paypal_account (char field) to a payment.acquirer
and company.paypal_account becoming a function field, with a getter / setter.
This function field is company aware.
- added an update of the res_config view of invoicing to link to the list
of acquirers
- added possibilty to install acquirers from invoicing (paypal / ogone / adyen
are installable through config)
