Get rid of the 1-char subtitle type field. Use sh_stream->codec instead just like audio and video do. Use codec names as defined by libavcodec for simplicity, even if they're somewhat verbose and annoying. Note that ffmpeg might switch to "ass" as codec name for ASS, so we don't bother with the current silly "ssa" name.
