Variables are now at module level because they have to be mocked when there is
an `ImportError`, so we got an `AttributeError` when trying to use them.
Otherwise you can get errors like:
```
from . import reporting_xls
File "/opt/odoo/available/OCA/l10n-spain/account_balance_reporting_xls/report/reporting_xls.py", line#
Please enter the commit message for your changes. Lines starting
31, in <module># with '#' will be ignored, and an empty message aborts the commit.
from openerp.addons.report_xls.report_xls import report_xls# On branch 8.0-report_xls-protected_import
File "/opt/odoo/available/OCA/OCB/openerp/modules/module.py", line 80, in load_module# Changes to be
committed:

File "/opt/odoo/available/OCA/reporting-engine/report_xls/__init__.py", line 24, in <module>#
from . import report_xls
File "/opt/odoo/available/OCA/reporting-engine/report_xls/report_xls.py", line 63, in <module>
class report_xls(report_sxw):

```
[FIX][report_xls] Protect import.
Even after merging 2bf93a1d49, import still breaks when trying to use module's stuff at class definition time when module is not imported.
I move xsl types to a failure-safe scope.
In order to get visibility on https://www.odoo.com/apps the OCA board has
decided to add the OCA as author of all the addons maintained as part of the
association.
