Subject: [PATCH] Playback cursor jitter when scrubbing backwards

Currently the jitter in the playback cursor is worse when scrubbing backwards than forwards.

Fix:
In AudioIOBase::PlaybackSchedule::AdvancedTrackTime()
in the line:
time += realElapsed * speed;
realElapsed is negative when scrubbing backwards, so need fabs(speed) rather than just speed.
