Target ClojureScript

[roman01la]

Tracking PR for #11

What've been done so far

• [x] Setup ClojureScript build
• [x] Setup testing for ClojureScript
• [x] Move shared code into schema-refined/core.cljc
• [ ] Rewrite -def-map-type macro for ClojureScript (mostly protocols and interop)
• [x] Move Clojure & ClojureScript code for guarded structs into separate namespaces due to substantial differences
• [x] Adapt ClojureScript tests to host platform

More comments

• cljs's -def-map-type macro is not entirely done yet
  • Not sure about JS interop yet (should it be js/Map or js/Object etc)
  • There's a bug somewhere that causes stack overflow in tests, haven't tracked it down yet
• Schema coercion doesn't work as expected in ClojureScript, bc CLJS Schema extends js/Function type with its protocol which leads to different coercion results
• Run tests with lein do clean, with-profiles dev,1.9 doo node test once (only Node for now, couldn't get it working on Nashorn)

Not sure it's worth spending time on Nashorn due to this http://openjdk.java.net/jeps/335
