GT Extensions for FluentCart 2.8.1

New option to number invoices with FluentCart's invoice numbers. Choose it under Invoices → Invoice appearance → Invoice numbering. An issued invoice and its FluentCart order then show the same number, such as INV-1253, instead of two different numbers. Invoices and store orders share one series, so the next store order takes the number after the invoice.
The number stays with the invoice when the customer pays in another currency or you edit and reissue it, and a cancelled invoice keeps its number. Invoices issued before you change the option keep their numbers. GT Extensions numbering stays the default.

Requires FluentCart. Invoices and the other store modules require FluentCart 1.6.4 or later.
