- Added the capability to load up to 4 sound drivers and added methods to get pointers to the waveout, wavein and midiout services of a driver. - Rewrite of the SB16 midi file output code. In midimode 2 and 3 the midiout service of the 'file' driver is used. Removed obsolete midi file handling. - Re-implemented the closemidioutput() method to make runtime changes of the midi setup work with the new code.
