Commercial component - content API

This adds html and styling for the commercial component that is driven from DFP and uses the content API for it's content.

There is more work to be done on the DFP side to allow easier entry of chosen stories.

These are in all of the commercial components, was like it when I got here!

They are used to create the tracking codes for links inn each of the components, I then bump the numbers up each time something is changed in the components.
