Fixed #286 (Probably). Refactored the subtitles loader so it downloads the subtitle and then parses it in-memory, getting rid of CORS issues and the only reason we kept the TMP folder there.
Since that was a huge piece of crap, this should get rid of all subtitle issues in Mac and some Windows installs, since you can't write to the app folder. This also makes the app more efficient, since we only download the subtitles on demand.
Also rewrote the movie model so providers have to return standard movie models.
