on a fresh install, browse the FS for downloaded dharma talks #35
Description
If the user downloads some talks and for whatever reason deletes and re-installs the app or deletes the data, the dharma talks will remain on their device (which I intended), but we will not know that those talks are downloaded. So on boot up, we should check the DIRECTORY_MUSIC/dharmaseed folder for dharma talks and update any talks in the DB. This will prevent confusing behavior if I downloaded a talk, uninstalled the app, re-installed, and then clicked that talk in the app - the app would not recognize I had downloaded it and I would have to download it again.
