Update datomic schema, add initial data

Schema to match the card_schema.cljx
Initial deck to (mostly) match the current model.cljx
Datomic schema now supports cardtypes and actual physical cards as two seperate concepts. A deck has many physical cards and each card has a card type.
Such WIP.
More WIP.
Merge branch 'deck-builder' of github.com:cape-town-clojure/steel-plains-tcg into deck-builder
