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

from . import report_xls

```
[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.
