auto debit second card option (fallback)
It would be nice for clients to be able to select more then one auto debit options. This would serve as a backup option to the main auto debit option. Example would be, client card gets declined so it tries the next selected card for auto debit. Blesta then would send an email saying primary auto debit got declined and secondary account was used. This would be helpful for clients to not have their service suspended while they resolve their primary card issues.
