Add EnginesFXController
Tweaks to EnginesFXController

Probably not quite ready for prime-time.
Add experimental APAS-69 fix module

Seems to work, sometimes.  Fixes the rotation of the docking node
transform so +Z points forward (which seems to be the requirement for
docking nodes).
Add option to AxisRotationCopy to limit angle rate

New field, axisResponseRate, indicates maximum degrees-per-second the
transform can slew.
