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

That's what I thought at first and at first I named the parameter companyGuid.  The first pass of mapCompanyId used companyId to pass in the guid and at first I didn't understand why, but now I see it's because the parameter you want to pass in is companyId, but on the client side you only have the guid. If you name it companyGuid then you run into trouble where you don't know if you really want companyGuid parameter and when you should delete it so it doesn't cause errors with the ORM methods.
