Changed
- In the config file, the `player.transition_duration` is moved to `player.durations.transition_duration`;
- To run the player, invoke the command `dakara-play-vlc` or `python -m dakara_player_vlc`, instead of `dakara.py`;
- Configuration is now stored in the user directory. You can create a new config file with the command `dakara-play-vlc create-config` or `python -m dakara_player_vlc create-config`.
