Title: Added 'on demand' option for products/variants

Added an on demand option for products and variants whose inventory should not be tracked as they are produced on demand or shipped by a third party.

It's my serious pull request so:
1. Pull with caution.
2. Any feedback appreciated.

[fixes #1940]
