The GUI code has been reworked, now it's more optimized and bug-free.
New playlist system : you can choose between the temporary Playlist (which is removed after a reload), and your Favorites song (which is stored in your datas)
Menu system in the bottom of the GUIs :
Options : volume/join/shuffle/particles
Playlists : empty the actual playlist, next song, choose playlist
Description of songs is now splitted (now it should not exceed the screen)
In admin commands, "@all" has been changed to "@a".
