Can play audio

- Threads set as daemons so that they will terminate when application
closes.
- Player class to play music, currently music is played when you upload
a file (not youtube URL)
- Added audio player class
- Removed channels API and added audio file tag library
- Swapped FLAC and MP3 order on file browser
- Currently the audio stream randomly freezes (4/5ths of the time).
Gotta figure out the cause of that.
