A new column ledger in the stock table and some related keys
(stored in erp5_mysql_innodb_catalog) have also been created
Adds tests for inventory queries based on ledger in testInventoryAPI

erp5_core: changes portal type filter on dynamic_class_generation_interaction_workflow and base_type_interaction_workflow to a portal group filter

These workflows now apply on every type belonging to the grouping type 'type_definition': Base Type and other portal types of portal types

ERP5Type: introduces 'type_definition', a grouping type to identify portal types defining other types

ie: Base Type and portal types of portal types

erp5_accounting,erp5_project,erp5_payroll,erp5_trade,erp5_open_trade: changes base type of Deliveries to Delivery Type

: Orders and Packing Lists portal types now have Delivery Type as portal type

For the moment it only allows to define a list of ledgers
on the portal types inheriting from it, to create a filtered
list of ledgers allowed on the final objects.
Adds DeliveryType.py, a new Base Type for Delivery portal types
Adds testTypeDefinition.py, a new suite to test DeliveryType

_viewAccountingTransactionList forms can filter on preferred ledgers.
Preferred Ledgers can be set in preferences.
Form fields related to ledgers are not intrusive and don't display if None is defined.

Which was related to an older version of the simulation

For example, Python Scripts were:
- dirty in the imported BT (causing all of them to be reinstalled on upgrade)
- compiled to return None

When a currency exchange line is (in)validated, we need to reindex the currency exchange
cells that acquire validation state from the currency exchange line.

This allows defining an exchange rate without end date

Mark the test as expected failure for now.

This test is in expectedFailure state and is still not passing with this
change, but this test was showing wrong example that can cause
confusion.

Here are 2 examples of fixed cases:

- File object with data=None was exported with a second file containing the
  string 'None'

- Zope Pages Templates (and derived OOoTemplate) relied __setstate__ to fix
  the wrongly imported object.
