[development] New module: E-Commerce Product Location

I've been working on a product that needed locations. Rather than write support for locations into my product type module, I wrote a module that allows location module settings to be configured for any product type as they are for content types. I will be gone for a few days, but when I get back I will release this as a stand-alone module unless there have been similar efforts or plans for E-Commerce location integration that could use my contribution.
