Adding customization options to the helper gizmo to allow visual distinction between e.g. hand IK controllers and elbow IK targets.  Helpers can now have their color customized and have six more options for shapes: Dot, Cross, X, Circle, Polygon, and None. The new shapes respect multidimensional scaling, so permutations such as ellipses are possible.  An additional cross and/or X can be drawn on top of the selected shape, allowing further differentiation between otherwise similar helpers.  Helpers can also have their size frozen so when the scene camera zooms in/out the absolute size of the helper remains the same on-screen.
