Davor is downloading and caching the API responses into the packaged app itself so it can read that from disk on first load and be super fast. This bug is to investigate and implement how to cache the icons and screenshots in the package. Icons are a higher priority than screenshots if there is a need to choose one over the other. We also will likely need to limit the number of screenshots per app.

Note: in an effort to reduce the package size, this was backed out to only include icons, excluding screenshots and thumbnails, for the time being. https://github.com/mozilla/yogafire/compare/72baa0df0c0f...308a0e72ebcd
