Airplay support

[OwenRay]

Should support the same features as the currently implemented ChromeCast support:

• play/pause
• seeking
• subtitles
• different audio/video streams
• volume

At least on Apple mobile devices, playing a movie in fullscreen will automatically add an AirPlay button.

🤔 I wonder if that's enough, (it may be)
I don't have an apple tv so I wonder if it will work:

• Will it play at all? (I'm mainly concerned about codecs)
• play/pause
• Switching audio/video streams
• Subtitles
• Will it support skipping to the next video in the playqueue.
