Enhanced Credit Checking

Modifies the credit checking process in Accounts Receivable Invoice Entry, Sales Order Entry, Sales Order Invoice Entry, RMA Entry and RMA Receipts Entry. Two new role maintenance Module Options have been added: 'Allow Credit Terms Override' and 'Allow Credit Hold Override'. The existing Module Option to 'Allow Credit Limit Override' will now check only the status of the credit limit. Also adds a log file to track which orders/invoices have experienced Credit Hold, Credit Limit, or Credit Terms overrides as well as recording who performed the override.
