- failure in callable does not throw error
- recursive tales support

This should fix bug 2071215-1637B3D
The fix was done by removing (commenting out) code which was making ERP5 possible to somehow use offline with the new UI.
Now the possibility is shrinking in favour of backward compatibility.

e.g. `activate(after_path=())` should ignore `after_path`

And move gadget global

Most properties of test suite and test suite repository were by mistake set with type "lines" instead
of strings. Due to this, constraints where not working (for checking missing properties). Also, workflow
was not properly set to check constraints. So at the end, most constraints were ignored.

Change properties from type lines to type string. Add test for constraitns. Add compatiblity code
to do transparent migration of existing tests suites and test suite repositories.

Remove obsolete properties and constraints.

This prepares for the removal of --firefox_bin and --xvfb_bin options. The
API between the testnode and the tested software must be exclusively generic.

generateMovementListForStockOptimisation was raising error when there was inventories.
The method was assuming that doing getObject() on an inventory line (from
getFutureInventoryList) was always returning a movement. But sometimes we get
the inventory itself. So do not use getVariationCategoryList, but use the variation_text
stored in the stock table.

- Allow superuser to get RSS ;
- Remove useless portal_skin=RSS paremeter.

Allow user to select which columns to display on module.
A new panel has been added for the UI.
The selectable column list is calculated from the columns and all_columns parameters.
Configuration is for now stored in the URL (as sort).

[erp5_pdm, erp5_trade] Fix bad field library field id. Rename ledger field library proxy field from my_ledger to my_view_mode_ledger.

[ERP5/tests/testERP5Commerce.py] quantity_unit/unit/piece category is used but it does not exist in this test. Add quantity_unit/unit/piece in afterSetUp.

To use non-existing category may lead an unexpected result. This time, getAcquiredCategoryList did not work correctly, then category values of products were not correctly indexed and test_17_getProductListFromWebSection failed.

Revert "[ERP5/tests/testERP5Commerce.py] Add erp5_configurator_standard_categories business template to provide quantity_unit/unit/piece."

This reverts commit 93c6b048.

erp5_configurator_standard_categories depends on too many business templates. I gave up using it.

[ERP5/tests/testERP5Commerce.py] Add erp5_configurator_standard_categories business template to provide quantity_unit/unit/piece.

To use non-existing category may lead an unexpected result. This time, getAcquiredCategoryList did not work correctly, then category values of products were not correctly indexed and test_17_getProductListFromWebSection failed.
