Rename CollectionAndConfig FaciaContainer, make display properties explicit there

Sorry, another minor refactor :cry: 

As we're about to change the tag pages so they behave more like fronts, I wanted this done so that I wasn't having to do weird things like construct Configs with IDs that would resolve to the containers I wanted, etc., in order to build the page up.

If you want more details as to the wherefores come over and ask!

I think it does make things a little cleaner, too (similarly to what we did with FaciaCard).
