Add more support to OGM in BSI and command line

[Mich Buchanan]

Actually BSI files doesn´t work with OGM media (at least not all the BSI like choose the default subtitle, and audio stream, font for subtitles), and the command line doesn´t work too, it would be nice to add this feature.

PD: Sorry for my poor English.

I agree with that. OGM is becoming more and more in use.
It's a bit annoying that you cannot define default streams in .bsi files (no effect) and whenever you switch during playback the player falls back on first stream when changing to 2nd CD. But last comment is on a common issue as far as I remember, not only OGG/OGM related...
