Initial card name localization support

Will allow (via some kind of UI interface) users to link to a
JSON file to load "localized" versions of card names instead of
things like 'Card02003'

JSON file should be in the format of:

  {"Card00001": "Card Name", "Card01003", "Other Card Name"}
[debug] Add local copy of localization file if present
