Inline commercial component version2 styles

cc @paulrobertlloyd 

This gives styles to version 2 of the inline commercial component once the template in DFP is used.

Will also replace the styles for new inline books component, (and add some logic to take care of overly large book covers.)

Before & After in one screen, (after on the left, before on the right.)
