(svn r5464) [Behaviour Fix] : When starting the game, the system will now verify the presence of music files in gm forlder.
A song can now be removed from the programmed list (in custom list 1 and 2) by clicking on it.
Added music.c[ch] files, to make it all a bit cleaner.
Now, the name of the gm file is associated with the title of the song.
