Bug #649992: Let owner-report aging table include due date / post dat…

…e options in aging.

Patch by "Bert":

Follow up on bug:
https://bugzilla.gnome.org/show_bug.cgi?id=502066 #502066 called "The aging in
business reports should use the due date instead of the post date".

In that bug the aging reports were extended to use the due date when reporting
overdue in buckets such as Current - 0-30 etc.

This created an inconsistency since the owner reports (such as Customer Report)
did not report the Current bucket and did not include the option to select Date
Posted or Date due.

The attached patch patches the owner report to:
*Allow a choice between the use of Due Date and Date Posted
*Report with the current bucket
