erp5_accounting: replaces "here.portal_preferences" by "preferences" in TALES expressions in Account_viewAccountingTransactionList (fix for 994e3555)

erp5_accounting: replaces "here.portal_preferences" by "preferences" in TALES expressions in Entity_viewAccountingTransactionList

erp5_accounting: adds "ledger" in the extra columns of AccountingTransactionModule_viewAccountingTransactionList

erp5_accounting: removes "ledger" column from the listbox in Entity_viewAccountingTransactionList (fix for 994e3555

erp5_accounting: removes "ledger" column from the listbox in Account_viewAccountingTransactionList (fix for 994e3555)

test_account* and test_entities*: updates index of some element since addition of new column "Ledger" in Account_viewAccountingTransactionList and Entity_viewAccountingTransactionList

erp5_accounting : preferred ledger form field only displays ledgers defined on accounting transactions types. The field doesn't shows up if no ledger is defined nowhere

erp5_core: new stock.ledger_uid column taken into account in Resource_zGetInventoryList and Resource_zGetMovementHistoryList

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_accounting, erp5_payroll: init scripts for accounting types now call a generic Delivery_init first

erp5_base: adds a Delivery_init script to set up a default ledger on new objects which portal_type inherits from "Delivery Type"

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: changes type of main Accounting and Task documents to Delivery 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.

It allows to set up the default ledger on these documents too

New accounting documents belong to some "ledger/accounting/X" category
  if such is defined in the accounting preferences.
Accounting views of some documents now include a ledger.
_viewAccountingTransactionList forms can filter on preferred ledgers.

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