#add Added a new FUICommandList::ProcessCommandBindings overload, which can be called from a Viewport Client's InputKey() method (in the absence of an FKeyboardEvent object).
#add Fixed key binding handling in SplineComponentVisualizer so that it works through the FUICommandList, instead of being hardcoded.
#change USplineComponent - changed method by which spline reparam table is created (now uses the old method of splitting each segment into a fixed number of steps, instead of using fixed arc length reparameterization, which doesn't lead to such good results where the distance between control points varies largely throughout the spline). The ReparamStepsPerSegment parameter remains, although I'd like to remove it when I can hit upon a better way to adaptively step through the spline. Merged UpdateSplineReparamTable and AutoSetTangents into a single UpdateSpline method.
#add Added a parameter to FInterpCurve::AutoSetTangents - bStationaryEndpoints - which determines whether the endpoints should be assigned zero tangents, or whether the tangents should be set in order to extrapolate the curve beyond the endpoints, essentially providing a constant velocity at the start/end.
#add Added bStationaryEndpoints as an editable parameter to USplineComponent. Use this if you only wish to traverse the spline at constant velocity, as it will lead to more accurate results.
