Simply Invoices

Many thanks to Андрей Руденко for providing me with a Russian translation. You may now create invoices in Russian and with the руб currency.

Also in this update is the ability to edit the invoice number by hand. Editing the invoice number only changes the invoice number for that invoice, it does not effect the incrementing counter for the invoice template.

Both of these changes were driven by users. Please do email me or stop by the chat room if you can provide a translation, have a feature request, a support issue or just want to chat.
