Utility functions use mat4 instead of Mat4

[ulf.schroeter]

Problem

 

In data\core\scripts\utils.h functions getTransformDirection/Rotate use mat4 instead of Mat4

....
Vec3 getTransformDirection(mat4 transform) {
	return -transform.m02m12m22;
}

quat getTransformRotate(mat4 transform) {
	return quat(orthonormalize(transform));
}
....

Thanks, fixed.
