have the annoying dialog closed after 10 sec.
this is especially for the autoplay-stuff,
since I've got 3000+ songs and a few of them have broken notes displaying this dialog (songs just play fine)
I will use performous next tomocon where it will be on autoplay when i'm not there so it's really annoying having this dialog cover the songs until i return!
updated Japanese translation

Set full instrument track volume at start. Closes #66.
Fixed program "flow" when autoplay hits a duet song & display score for
dance/guitar even when karaoke-mode is enabled.
display the second line in duet mode
 - because it's very annoying if you don't know the lyrics and lines
just "suddenly" pop up
