Subject: stats: make the OSD usable in audio-only mode

Previously, the script would throw garbage (ASS tags) at the terminal
when the bound key was pressed. This changes the behaviour to _not_
print any ASS tags (and replace those which can be interpreted by the
terminal) if there's no video.

I cleaned the patch up since you mentioned you were busy. As I said
before, there is absolutely no problem with calling mpv to display
strings to the OSD without any video. They'll just go straight to the
terminal just as they would with an active VO.
