[ADD] account_cash_basis_base_account: add module to change the base amount account in tax cash basis entries

To be able to retrieve the base amount of cash basis taxes lines, additional journal items are created for the base as well in the journal entry generated by the payment.
However, these additional journal items debitting and creditting the same account are considered as pollution in reports.

This module and hook allow to move these additional lines to an another account, if needed.
