Object copy

[Frankie Bagnardi]

I'd like Object.merge(source, dest), and Object.clone(source).

Object.clone would be best if it cloned almost any object, like more
advanced clone functions.  This includes plain objects, arrays, instances
of classes (preserving base class, etc.), regExp, promise, and ideally DOM
nodes in browsers (along with anything else that can be cloned).  If
something can't be cloned, including primitives and functions, it should
throw an error.

Object.merge would be a much simpler "copy enumerable own properties"
function.

Object.merge({a: 1}, {}); and Object.clone({a: 1}); would be equivalent,
but they differ in most other cases.
