Better display of contacts, simplified contact creation, use default image
for shipping and delivery, and various fixes and improvements in the
form view.
Main impacted addons :
- account: add a bank_account_count field and stat button that replaces the
2many field
- base_vat: remove the button to check vat, as there is already a constraint
and removed and unused import
- payment: add a payment_method_count field and stat button that replaces
the 2many field
This commit adds a new model, Payment Method, which stores
a reference to the payment acquirer's database and a reference to
a partner. Each payment module must have its own implementation.
The implementation is completely abstract but may not suit every
provider's way of implementing recurring payments.
