The Belgian localization has been updated to reflect the official Charts
of Accounts.
Users now have the choice between the official CoA for Companies or the
one for Associations and Foundations.
All related terms and translations have been reviewed and corrected in
the 3 official languages (nl, fr, de).
Non-official languages have been removed, since they both don't make
sense and they did not work because of targeting an ancient version of
Odoo.
Finally, the 580000 account has been set as the default Internal
Transfers account, avoiding a second 58 account to be created.
