Before this change, `index_html` for Catalog Tool was None that means trying to
access view for CatalogTool from UI always make a function call to the
` __call__` which function was overridden with `searchResults`, which
means everytime someone tried to access `portal_catalog/`, a useless query was
being made and an undesirable query result was displyed on the UI.

In this case, `index_html` is prefered whenever we try to access portal_catalog
from UI.

Also, add test for proper display of view when CatalogTool is accessed from XHTML UI

* Problems with data migration ( some events had no source, the logic of using current user was anyway wrong ) 
* Problems with security
* RSS too small

( see commits for details )

.pop .popitem and .setdefault where returning None

Security might be configured in a way that even if user can see the
support request he cannot see all events related to that support
request. We should handle this case by filtering out the event and not
letting Unauthorized error happen.

There was an issue that RSS was failing with Unauthorized errors when there was some events users cannot access.

(once again, thank you zope security, it was not leaking information just causing error)

default of 5 is not enough and must have caused people to miss messages ( when more than 5 messages are posted between 2 refreshes from their RSS reader)

Project use case: Use modification_date instead of operation_date to export
ATs modified the day before.

erp5_accounting_l10n_fr: Allow to pass additional Catalog parameters to select Accounting Transaction to FEC export.

Introduced for customer Unit Tests to be able to FEC export only ATs of the
current Unit Test FEC based on 'title'.

Called by TransformationSimulationRule and did not work with the
following use case:

  BL(trade_phase=TP1, successor=trade_state/TS1):
    * child_BL1(predecessor=trade_state/TS1,
                trade_phase=TP1/InventoryAccounting)
    * child_BL2(predecessor=trade_state/TS1,
                trade_phase=Transforming)

.. not the current logged in user.
This way, it's possible to run the post ingestion as another user, for example
running by an alarm or as a data migration.

bt5/erp5_scalability_test: Remove a Permission Configurator Item. It depends on standard_module_permission_access.ods, but it was already removed from erp5_configurator_standard skin folder.

in accounting_module and sale_order_module listbox.

The "Sale Trade Condition" column was showing first found specialise title
instead of the Sale Trade Condition one.

This adds z_related_specialise_trade_condition with related key specialise_trade_condition_title
and an accessor getSpecialiseTradeConditionTitle

We edited the HTML, but did not include the accompanying increase of modification date.

When a workflow transition was not used by any state,
calling some_module.Module_listWorkflowTransitionItemList was raising:
    [..]
      Module script, line 49, in Module_listWorkflowTransitionItemList
       - <PythonScript at /tsxx/Module_listWorkflowTransitionItemList used for /tsxx/some_module>
       - Line 49
        result['listbox_parameter_dict'][transition_id] = [(state_variable, allowed_state_dict[transition_id])]
      Module AccessControl.ZopeGuards, line 83, in guarded_getitem
        v = object[index]
    KeyError: 'some_action'

Now, pick transition among the allowed_state_dict instead of workflow.transitions.

This also fixes mass change state dialog "??? ()" issue.
This commit adds a transition that allows to reproduce that issue.
And this line covers the case :

Some things in support request app where working apparently a bit by chance and they no longer work with new erp5_hal_json (
09d00cae )

This aims at using erp5_hal_json as intended and simplifying the customisations by customising "only" the header gadget and not the page gadget.

/reviewed-on nexedi/erp5!787

erp5_real_time_inventory_accounting: Accounting Transaction state should be 'Posted to General Ledger' (stopped), not draft.

erp5_hal_json does not seem to allow using gadgets by page name,
anymore, so instead of using a custom "page template" gadget (
disclaimer: I have not really understood this fully at this point).

Instead of using a custom page gadget, just use a header gadget that
"extends" the default gadget but removes the add_url

Because the fast input should be used.

Also simplify a bit the test, there's no need to add a SR in this case.
