. fixed a few warnings at compile-time . fixed sound channel selection in playlist mode . added a color message in the plugin bank because on peut bien d�conner cinq minutes, quand-m�me . we now spawn a new input thread for each file . added a missing pf_close() because it's always cool to close files after we read them
