mplayer: prefer -sub/-subfile subs over auto-loaded subs
Before this commit, it was more or less random which subtitle was preferred if there was both an auto-loaded external subtitle, and a subtitle loaded via -sub or -subfile. -sub subtitles happened to be preferred over auto-loaded subs, while -subfile didn't. Fix the -subfile case, and make the behavior consistent by making the selection behavior explicit.
