Move new Facia card CSS to head common

This article (/commentisfree/belief/2012/oct/19/can-massacres-cromwell-ever-be-justified) on CODE is messed up because a Facia container is loaded by AJAX. On CODE this container is a new-style Facia Cards container, but the CSS does not exist for those containers on article, so they render like crap.

This moves the CSS to common, which is where it's going to have to be eventually anyway, when we switch article over to use new-style containers.
