Multiple commercial loader & "frankenponent"

This gives the ability for the commercial loader to take multiple values (by @ironsidevsquincy).

We then use that facility to load multiple small components into a master component.

The order and choice of components is controlled via DFP in a custom component, choices of components are Masterclasses, Jobs, Books, Soulmates & Travel.

Releasing this means it can be shown behind an ad cookie.
