Log:
[Imp] IT: Disable a few more compatibility flags for older SchismTracker builds (https://bugs.openmpt.org/view.php?id=1764). Only a few flags from the proposed patch have been carried over as the implementation for some of those effects was too different between Schism Tracker and OpenMPT, potentially causing OpenMPT's old bugs to be applied to SchismTracker where they were not necessarily "correct".
