CloudArchive and CloudModel complete (enough)

- CloudModel is actually classed correctly
 - Minify JSON prior to uploading
 - Change archive update interval to 24h (30* ..20MB = 600/1000MB)
 - Store latest revision url for archive/model after persisting

TODO:
 - Add INITIAL_CORPUS_FILE config var
 - Look for Cloudinary API call to get filesize w/o DLing
 - Logic for jsonify(INTIIAL_CORPUS_FILE) v. using persisted archive
 - Add fetch/persist/etc methods to Ebooks::Archive/Model for fallback
 - Test it? Or just share it and pray.
