v0.2.8

New

• HTTPS for RadioMaster Server (--https): use your own certificate (e.g. Let's Encrypt) or let the
  server make a self-signed one, which the app shows by its fingerprint and trusts once you agree. The
  app warns if the certificate changes later
• Web portal for RadioMaster Server (--portal, port 9260 by default): run the station from a browser,
  including on a phone, with what's on air, the transport buttons, volume, playlists, streams, history
  and the log
• Connect to Remote Server on the login screen: sign in with the server's account without a local login
• Settings → Devices → Sound card buffer: Low delay, Normal, Slow computer or Very slow computer

Fixed

• Playback stuttered on slow PCs: songs are now decoded ahead on their own thread and the sound card gets
  a bigger buffer, so a slow disk or a busy CPU no longer causes gaps
• Playback stopped (and Play did nothing until a restart) when another app such as Spotify took over the
  sound card; RadioMaster now reopens the device within about 2 seconds and keeps the stream and
  automation running in the meantime
• No sound in the app while connected to RadioMaster Server: the app now plays the station's on-air mix
  on its own outputs ("Hear the station here" in the connection window turns it off)
• The Mic button while connected to a server: your microphone now goes to the server and on air, with
  the station's mic settings

Changed

• Less work on the UI and audio threads: faster Search tab and file explorer, event plugins start in the
  background, and unchanged files aren't rewritten on every save
• Website: a RadioMaster Server page and a "How to start an internet radio station" guide
