Subject: Re-namespace some stuff to Omni

I was getting confused about what is a product and what is internal
infrastructure; I think it is good to keep those things separate. So I moved a
bunch of stuff to an Omni namespace, actually most stuff went there. Only things
that are explicitly external products are still in the Biz namespace.
