Minamp 1.2

Browse Source 
- Transcoding: send client identities Plex has a profile for (unknown ones get
  400 "unable to find a matching profile"), with a fresh session id per variant
- Stream proxy: fetch transcodes once into a temp file and serve every player
  request from it, so reconnects no longer restart the transcode (503s, tracks
  cut short); original files still pass Range requests through
- Sign-in: remember the pending link code so it survives Minamp being closed
  while the code is entered elsewhere; add "I've entered it - check now"
- Diagnostics: in-app connection log (DiagLog) with a streaming test and save
  to SD card; tokens are never logged
