Make wires selectable and deletable with Delete key #9

Click on a wire body and have it visually feedback by showing it is selected
Then be able to hit Delete on the keyboard to remove the connection (or trigger the delete by way of a method)

This is important for graphs that allow multiple wires connected to an input port (e.g. event-based things like midi routing).

I couldn't find any functions in the apple apis for hit testing against bezier strokes. A reasonable method would be just to subdivide the bezier path and early-reject segments that don't intersect with a query rectangle.
