Commercial dfp single, adding Soulmates logo option

This adds the Soulmates logo across all breakpoints.

In DFP the single component template now has an option to select logos for Soulmates and Jobs, these add simple classes into the template. As there is no logic in DFP templates we have to resort to some awkward css :(
