Reroute nodes, by Jeroen Bakker (patch #28443).

By holding shift and "cutting" a node link a new reroute helper node can be inserted. This consists of a single socket that can be used to insert additional connection points into a link. This can be used to keep a connection point in the tree when  deleting a node, or to control the path of long connections for layout cleanup.
