tell business template to keep z_catalog_stock_list when upgrading
erp5_calendar

Because CatalogTemplateItem uses a special preinstall method, their way
of computing modified objet did not support template_keep_path_list.

To support template_keep_path_list, we must give priority to
ObjectTemplateItem.preinstall, because BaseTemplateItem.preinstall does
not work with path.

ERP5Type/tests/testERP5Type.py: Put expectedFailure mark to test_PropertySheetSecurityOnAccessors. Permission definition on Accessor is buggy. It has to be fixed.

Allow to switch from editable/viewable mode directly from the panel.
Drop editable/viewable button on tabpage.

The editable parameter is propagated by all links.

ERP5Type/tests/testERP5Type.py: Make sure that accessors are protected correctly when permission was specified in the property sheet.

erp5_ui_test: add do nothing reports to Foos
erp5_web_renderjs_ui_test: add export button ui tests

Since a process might exit by himself at any time, handle exceptions when
we try kill processes

Spotted by chance. Seems unlikely to be hit, but that would be a stupid
arbitrary limitation nevertheless.

ComplexQuery bypasses SearchKey mechanism and makes assumptions
SQLCatalog.{search|count}Results does not do.
Instead, reserve a name, and complain if it is passed by caller.

"query" argument is not supposed to be different from any other
argument (argument name is [pseudo-]column name, unknown coluns are
rejected, and "None" means "IS NULL" SQL comparison), but is accidentally
special-cased in ERP5Catalog. This special-casing is to be removed, so
update all callers relying on this glitch.
Also, avoid using Query.

Also, do not use deprecated parameter name to pass a logical operator.
