- Implemented the SVDRP command MOVC (thanks to Andreas Brachold).
- Added support for multiple audio language codes in ISO639LanguageDescriptors to
'libsi' (thanks to Marcel Wiesweg).
- Changed the audio PID language codes to hold up to two 3 letter codes, separated
by '+', to store separate languages broadcast in two channel audio mode.
- If the preferred audio language is broadcast on a PID that has two different
languages in the two stereo channels, the audio channel is now properly set when
switching to such a channel (thanks to Mogens Elneff for his help in testing this).
