Subject: [PATCH] Bug 6868 : Script to clean up accountno

This script cleans up damage to the accountlines table caused by the
writeoff()
subroutine in members/pay.pl (pre bug 3498 integration).

Includes two flags:

-t  Runs this in test mode.  The database is not actually updated; if
omitted, the changes run on database directly.

-v  Prints out every change made to screen; if omitted, just shows
progress counter

This script can take some time to run; 8000 updates in 5:30 minutes on a
powerful system, in my experience.
