Bezier curve handles snapping upgrade

    Bezier curve handles should have an option to snap to parallel and/or snap perpendicular to other segments/features. For a bezier curve to be tangential to another curve or straight segment the handle vector needs to be exactly parallel to the other line. This would make drawing smoother features like roads much easier.
