Weird bugs from .setIgnoreTimeScale(false) about leantween

[pmurph0305]

For anyone else having this issue, in LtDescr.cs, this is caused by the setIgnoreTimeScaleMethod setting this.usesNormalDt to false instead of !useUnscaledTime. It should be:

	public LTDescr setIgnoreTimeScale( bool useUnScaledTime ){
		this.useEstimatedTime = useUnScaledTime;
		this.usesNormalDt = !useUnScaledTime;
		return this;
	}

the same issue appears in the setUseEstimatedTime, and setUseFrames, and setUseManualtime which also automatically sets this.usesNormalDt = false instead of the appropriate value given the passed in parameter.
