A possible typo and undefined attributes - reportConstraints function

[Andrews54757]

Hello!

Ive been looking through your nice library and I found some puzzling things about the reportConstraints function.

1. Typo

It seems like there might be a typo here where .lenght should be .length

physics-module-ammonext/bundle-worker/physics-module.js

Line 3139 in 5f58d67

index = _constraints.lenght;

It also seems as if it was not fixed for quite a while.

2. .ta attribute is defined conditionally

The .ta attribute is set in the addConstraint function for the slider, conetwist, and dof types.

physics-module-ammonext/bundle-worker/physics-module.js

Lines 2527 to 2528 in 5f58d67

	constraint.ta = transforma;
	constraint.tb = transformb;

The .ta attribute is only used in the reportConstraints function for ALL constraints regardless of type.

physics-module-ammonext/bundle-worker/physics-module.js

Lines 3141 to 3158 in 5f58d67

	while (index--) {
	if (_constraints[index]) {
	var _constraint = _constraints[index];
	var offset_body = _constraint.a;
	var transform = _constraint.ta;
	var origin = transform.getOrigin();
	// add values to report
	offset = 1 + i++ * CONSTRAINTREPORT_ITEMSIZE;
	constraintreport[offset] = index;
	constraintreport[offset + 1] = offset_body.id;
	constraintreport[offset + 2] = origin.x;
	constraintreport[offset + 3] = origin.y;
	constraintreport[offset + 4] = origin.z;
	constraintreport[offset + 5] = _constraint.getBreakingImpulseThreshold();
	}
	}

Therefore, if you create a constraint that does not set the .ta attribute, you will get an error when this function is run:
