- expose the data as a writable store
- currently only supports raw HTML; example to come
- fix changes not marking a deck config as modified
- the data is currently packed into the deckconfig object, but we
may move these to a separate store in the collection config in the
future, like is done with decks/notetypes
- try out bootstrap modals - they're not perfect, but let's see how
they go for now. Won't be hard to switch to bridge commands if required.
- handle adding/renaming/removing
- add a class to manage the state
