7.0 Added modules 'account_voucher_remit_to' and 'account_check_writing_remit_to'

In countries where payments are made by checks the account vouchers are used, and it often happens that the addresses that the checks should be sent to is different to the address of the supplier.

The new modules included in this PR add the possibility to link a partner to another partner using the "Partner Relations" module.
During the creation of a Voucher, once the partner is entered the partner's relations are used to determine the Remit-to address.
