Add a snap to the handle when it is on the center of the node

[Larryh]

When you put a handle on the center of the node, it does not snap to it, it would be good to have it

I am not sure if this is a feature a bug, since the interaction with the handle in the center of a node is unusual, as you can still see it behind the node when you select it and you can see it on top of the node when you select other node of the same object, and you have to select again the whole shape to be able to select the node again and not the handle
Gif to show the problem with the "feature" (I think this is not a feature yet implemented, It looks like it only closes the handle to the center but the handle still inoperative)

If this is a bug, I request to add the feature, to allow to remove one of the handles of a node (converted one side to sharp and the other side curved
By:
- Move the handle that you want to be removed to the center of it´s node
- An option in the node tool to be able to select and interact with handles (Allow the user to click on a handle and select it, so after that the user is able to interact with only that handle and be able to press DEL to remove it if want to)

FreeHand provided a pair of simple, elegant, Retract and Auto-Extend buttons in its excellent Inspector palette; one each for incoming and outgoing curve handles. You could, for example, select one or any number of nodes, and simply click the outgoing Retract button. The outgoing handles of all selected nodes would be retracted (i.e., made coincident with the node). This did not disturb the node type (Corner, Curve, or Connector).

The Auto-Extend buttons would extend retracted handles by the common 1/3 distance to the adjacent node, without altering their directions, if the node is a Curve.

To remove a handle, just Alt+Click it.  That will deal with request #1.
