prepl responses do not indicate if they're an exception or not

Question

When an error occurs in a Clojure prepl the exception is caught at the outermost layer and returned with {{:tag :ret}} as well as {{:exception true}}. This allows tooling to handle the error responses accordingly.

If ClojureScript would return {{:exception true}} as well it would bring it inline with how the Clojure prepl works.

If this is considered valid I'll submit a patch for it today. As far as I can tell from all of my work with prepls over the last few months this is one of the last major outstanding features. Once CLJ-2453 is in we'll have reader conditionals in both Clojure and ClojureScript too.

The only thing I haven't been able to do is set the current line / column / file path for ClojureScript evals, but that's off topic.
