-UI revisions to the deck editor. Still need to do a proper preview of cards; thinking of just doing a variant on the standard card markup for this (which should also be zoomable).
-UI elements in place for deck backs and card images. This hasn't been put through to the back-end yet.
-The deck-editor has been overhauled into something approaching "beautiful".
-The previews now match what you see on the table
-Still need to implement card back/card images. That's next up.
