Add "Create Sibling" operation

How about an option to create a "sibling"? Of course a module like "clone" doesn't work when the relativity data is not stored with the node itself. This would be extremely helpful to me.

I suppose it could be implemented by adding a "Create sibling" as a "Link operation" option but another possibility would be to work with "clone" to allow the appropriate relativity record to be created if a node using Relativity is cloned.
