Title: Added drag and drop node connection re-wiring.

In the Node Graph, users can drag nodes onto existing connections to see automated re-wiring suggestions. Dropping the node into the chain will perform the re-wiring (which is undoable).

Also added GraphGadget::connectionGadgetAt as a convenience for connection queries.

Fixes issue #78.
