BusinessTemplate: Get rid of spurious warning when skipping update of Local Roles for non-ERP5 objects.
erp5_property_sheets: Move Constraint Property Sheets and Views to their proper bt5s.

properties whose Portal Types (and sometimes their Views as well) were
available in a non-core bt5s.
erp5_trade: Portal Types of ZODB Property Sheets Constraint should be in 'constraint' 'group'.
erp5_forge: Migrate Glossary Extension to ZODB Property Sheets and Portal Types as classes.

DocumentationHelper and ClassTool removal.
ERP5Type: Support for Zope 2.8 has been dropped so set() can now be used without problem.
ZODB Components: Remove ClassTool and DocumentationHelper relying on it.
erp5_hr_l10n_jp: Removed as it's deprecated and unused.
