 * [new-owner-report] combined job/owner reports

In addition to today's earlier new-aging-report, the experimental submenu
will also have new-owner-reports i.e. customer/vendor/employee reports.
These are intended to replace old reports. Rewritten, easier to maintain.

Of note:
* will query customers/vendors/employees from all AP/AR accounts instead of
one, therefore the account option is removed
* will optionally show invoice->payments and payment->invoice links... also
supports unattached payments and invoices (i.e. prepayments and unpaid
invoices)
* the aging-table shares code with the aging-report, so, should show
identical aging details
* some assumptions were made re: correctness of book... damaged(*) books
may show a different owner report

Bugs etc still welcome.
(*) eg. whereby payments were made manually, and assigned to a customer
with a different currency
