Add basic support for Matroska ordered chapters. The switching between segments is implemented as a general edit timeline that could also be used for other purposes. Some things still need improvement. In particular the current code does not try to do any proper mapping between audio/video/subtitle streams of different files and there should be options for better control of how MPlayer searches other files for the required content.
