Clojurians Log v2

Thanks @bhauman, nice to know that it's not a bug. This ends up being a classic 'bad error messages' situation. I have spent a lot of time wondering why my code wasn't being called. (I'm working in about 10 namespaces, bouncing back and forth during long running REPL sessions). Maybe the figwheel REPL could add it's own message before the stacktrace? Like "[warning: last build contained warnings, try (build-reset) or :repl/help for more info]
