Release Unicorn

Unicorn is the first release I'm fairly certain is ready for public release as a non-"pre-release".

0.2: changed name of Player class to VlcjWind so instead of Player player =

new Player(width, height, vlcDetectionListener);
player.getMediaPlayer();
it would be VlcjWind vw = new VlcjWind(width, height,
vlcDetectionListener);
vw.getMediaPlayer();

0.1

moved some code around, nothing important
