Use ES7 spread properties to make shallow clones of objects.

I don't know if you have ES7 object rest/spread properties enabled, but, if you do, here's an easy ES7 idiom for creating a new object with all the same own properties of a given object.

Looks like this was the last use of footnote 3 -- can you delete that footnote? (after confirming it really was the last.)

I don't know very much about clone(), but does it do a deep copy or a shallow copy? The spread property only does a shallow copy, right?

[jeresig]

Yep - _.clone() is equivalent, so this could work. I think most of the cases that I've seen, that we had, were actually _.deepClone(). But there's no harm in adding this, as well. Would be good to delete (and re-org) the footnotes.

Perseus uses _.clone and, more commonly, _.merge pretty extensively, but has very few if any deepClones :). I think this is useful if we have es7 spread enabled.

OK, great -- once the footnoes are cleaned up I'll merge this!
