* 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.

* Upgrade base_export_manager to v9
* Rename JS to base_export_manager

* Change osv_memory to transient for model_id domain

* Improve UX for base_export_manager.

[FIX][base_export_manager] Fix "Expected singleton" bug.

If you had a field that got translated in more than 1 addon, you'd possibly getto this error:

      File "/opt/odoo/0079_ahk_openerp/oca/base_export_manager/models/ir_exports_line.py", line 105, in _compute_label
        field.name)),
      File "/opt/odoo/common/openerp/v8/openerp/fields.py", line 825, in __get__
        record.ensure_one()
      File "/opt/odoo/common/openerp/v8/openerp/models.py", line 5355, in ensure_one
        raise except_orm("ValueError", "Expected singleton: %s" % self)
    except_orm: ('ValueError', 'Expected singleton: ir.translation(4899, 703976)')

With this patch, now we let Odoo return the translated string by using its
standard method to do so, so we have to care for less.

* Move installation outside a data file.

This makes the whole installation to be able to roll back if something goes
wrong, instead of entering an error loop.

* Include envorionment in its manager.

* Add 4th field

* Move to api.multi, refactoring some stuff.

- Add some comments in complex parts.
- Rename `onchange_name` to `_onchange_name` (guidelines).
- Make `_compute_name`'s try block shorter and easier to understand.

* Allow R/W of name directly in model.

* Update tests to cover new behaviors.

- Remove all possible translation commits
- Aesthetical changes
- Bump version
- Some new standards, such as split readme

Basically, nothing.

If not, we are not assigning the label value for the record and we get
a missing cache value error.

WARNING odoo.fields: Redundant default on ir.exports.line.model1_id

Steps to reproduce:

- Create an export profile in any model.
- Login with a user without setting permissions.
- Go to export popup on that model.
- Try to select the saved export profile.

You'll get an access error.

Using sudo for computed/related stuff linked to ir.model,  we avoid
the problem.
