- Implemented wave output using the 'soundfile' driver including dual wave output in wavemode 3. Removed now obsolete output file handling and other cleanups. The wave input (recording) feature is not affected by the wavemode setting. - Moved VOC file handling to the soundfile code. - Updated iodev makefile dependencies.
