Possible Support for Both CLJ and CLJS Repls in single project?

[mikeball]

This is just a preliminary thought, but I wanted to post here for discussion.

It might very nice to have the ability to run both a clj and cljs repl in a single project. I know this is probably a complex/big feature, but it seems like it would effect the architecture of the entire extension so it might make sense to start thinking about it early.

Having 2 repls brings up some hard questions like how to handle .cljc files? Should they be sent to one or should they be sent to both repls on evaluation? What about errors coming back?

Or perhaps it should simply be 1 repl per editor and the clj and cljs editing should be separate?
