I should be able to clone a Thing

(User Story, Closed -> Fixed, Priority: Critical, Test Status: Unit tested , Reported By Bad Link: Thing 3y284oe not found, )
Summary:
The initial request from Eric:
(Possbly-relatedly-but-possibly-not, "Copy Thing" would also be lovely; there have been times I've really wanted to clone something, and doing so manually is tedious. AOK if it's console-only.)

Doing this console-only seems pretty straightforward, so let's consider this one seriously -- it's a reasonable power feature.
Indeed, should we think about this as a straight Querki function? Conceptually, it's pretty parallel to, eg, _createThing(), and would ideally want similar parameters. So we might consider implementing it that way, and just making sure it can be invoked ad-hoc from the Console...
