Volker Ruppert 0e73185efd Moved wave output support to a separate C++ class. The lowlevel sound module
creates the object and returns a pointer to it. TODO: The wavein and midiout
components should also move to separate classes. When finished, it should be
possible to configure the sound support more detailed (e.g. waveout with sdl,
midiout with alsa and the dummy driver for wavein). Creating a separate
module for the output to file(s) is also possible.
