Product file upload not work due to missing folder

[idseefeld]

The file upload in the products section fails, because it tries to write a file to the following path:
BlazingCoffee\Server\wwwroot\nutrition
But the directory does not exist and there is no check to create it first.

I propose to either
ensure the directory exists
or
create the directory in the repository
(put a dummy readme file into it, otherwise the directory will not be in the repo;-).
