* All engines: Implemented scheduler for delayed MIDI events and for
  suspended real-time instrument scripts.
* Real-Time instrument scripts: Implemented support for built-in "wait()"
  function's "duration-us" argument, thus scripts using this function are
  now correctly resumed after the requested amount of microseconds.
* Real-Time instrument scripts: Implemented support for built-in
  "play_note()" function's "duration-us" argument, thus notes triggered
  with this argument are now correctly released after the requested amount
  of microseconds.
* Real-Time instrument scripts: Fixed crash which happened when trying to
  reference an undeclared script variable.
* Real-Time instrument scripts: Script events were not cleared when
  engine channel was reset, potentially causing undefined behavior.
* All engines: Attempt to partly fix resetting engine channels vs.
  resetting engine, an overall cleanup of the Reset*(),
  ConnectAudioDevice(), DisconnectAudioDevice() API methods would still be
  desirable though, because the current situation is still inconsistent
  and error prone.
* Bumped version (2.0.0.svn2).
