A generalization of the modal node linking operator (for dragging from socket to socket).

This operator still had some built-in assumptions about the connectivity of input/output sockets (1-to-n in all current node systems). For future node systems (e.g. flow-based particles) and for general customizable nodes the operator is now fully symmetric and supports all kinds of connectivity limits (1:1, 1:n, m:1, m:n).

The operator data can also store a list of node links as opposed to a single link now, so that multiple links can be redirected at once. Holding the CTRL key when clicking a socket, all links from/to that socket are detached and can be moved to a different socket. This is useful for quickly appending a node without moving every individual link.
