* Improve UX for base_export_manager.
- Improve user instructions in README.
- Require some required fields.
- Allow to select models from a list.
- Allow to select up to 3 fields from dynamic lists.
- Improve translations.
- More tests.
- Translate column labels.
Some methods have been renamed, so version tag is raised to 8.0.2.0.0.
* Make inverse method be called at view time.
* Hardcode constraints in the `create` method instead of using normal ones.
Depending on the context where the record is created, it gets `resource` or `model_id`. The problem is that Odoo checks constrains before inverses, so constrains would fail always.
Test added to ensure future versions contemplate all use cases.
* Allow to reorder fields.
