Enhancements

• Modified QuickBooks sync to match the AccountingID on the additional charge instead of the name. This allows multiple additional charges to sync to a single QuickBooks item.
• When a zero invoice is encountered in QuickBooks we no longer attempt to sync it, since QuickBooks can't have a zero invoice. Quantify now sets the invoice to a status of Do Not Sync when this is encountered.
• When in single-rate mode you can now prorate the rental rates on your shipment to equal a specific amount.
