Multifunctional currencies on journal vouchers

To support defaulting of amounts in home currencies, currency details have been added to the header of journal voucher documents.

The functionality has been extended to also cater for tax transactions. The Tax Country, Tax Code and Tax Amount fields have been added to the document details. In the document header, a toggle option is available to view the totals either as a gross amount or a net amount, or only to view tax amount totals.

Additionally, several reversal options are available in the document details.

The same functionality has also been added to the multifunctional currencies import journal.
