Add sku and company guid to syndication. Add company guid parameter to all api calls.

I'm not sure exactly what you're envisioning but there are some issues.

The services are singletons so if we inject anything into them like $routeParams, they won't update if the route changes. 

Do we always send the guid in the header? How do we know what needs them and when to delete them on the backend so they don't cause errors the ORM?
