How RAVE treats Negative Variation Invoiceables/Credit Notes

Previously negative pending and accepted variations would be highlighted in red (say -$607.20) on the Progress Payment sub-tab.  However, now that we have changed to invoiceables and invoices this is no longer the case. It will now display in black i.e. $607.20.  

when you convert a negative variation invoiceable to a credit note, the dropdown menu option will still display as 'Convert to Invoice'. But the convert to invoice pop-up display will include a note 'Because this is a negative amount it will be created as a Client Credit Note.'.  This is because RAVE does not identify this as a positive (charge amount) or a negative (credit amount) until the pop-up appears.
