Support extenal .sup subtitles from Blu-ray-movies
As requested in: http://forum.videolan.org/viewtopic.php?f=7&t=51455&start=100#p317117
VLC 1.2.x can play .sup subtitles if they are in .m2ts files. But if those subtitles are in separate file, VLC cannot open them (unable to load subtitles from 'C:\00011.track_4622.sup').
