Another WorldBeatPlanet change

I got rid of the e-commerce module, which was a big pain. Instead I’m now using Amazon product nodes and I created a custom content type for CD Baby products. The store is now a new view which simply shows all Amazon and CD Baby product nodes. I can easily add other affiliates with the new arrangements. If I do eventually start selling music myself, I’ll create a separate store.worldbeatplanet.com domain, which will make it easier to maintain.
