Recurring invoices should have options for naming convention

Right now, all recurring invoice names have the naming convention

"#TemplateName#-#DueDate#." There should be an option to change the default convention to "#TemplateName#-#InvoiceDate#.The statement date for a credit card, for example, is often more helpful than the due date when seeing information at a glance since a statement that closes on 12/31 and is due on 1/28 is the "December Statement."
