Stock -1

Hi Claudio.
First Congrats, your plugin is the best of all pagseguro’s plugins.
My client used to put products with only one in stock. The store hides products with 0 in stock, besides some customers bought the same product at the same time, showing stock -1 in the end.
I have follow all your recomendations.
