Made content streams in HLS (.m3u8) format only run through HLS.js if on a non-Apple system as Apple devices (and AirPlay) support .m3u8 playlists directly.

Also added a dedicated cast button for content casting with Google Cast SDK, AirPlay/WebKit, and native device casting.

Finally, added an exclusive page at /exclusives/btsv for the ‘leaked’ unfinished Beyond the Spider Verse trailer.
