Fix ARAR Payment Method

This is #13 on the FXMENU maintenance utility for SCS use only and is not on a standard menu.

This utility can be used to change the 'Method of Payment' in Invoices posted to Account Receivable that are type P in the ARAR table.
 Orphaned Payment records preventing posting can also be deleted.

An audit record is written to the Audit Log for ARARFX to track data changes made by SCS staff through this support function.
