Vector3 angleTo() method mapping

[garthhenning]

The Vector3 mapping for angleTo() accidentally has the method name applyTo() and therefore the call fails from the Java side.

    /**
     * Returns the angle between this vector and vector v in radians.
     *
     * @param vector3 targeting Vector3
     * @return Vector3
     */
    public native Vector3 applyTo(Vector3 vector3);
