Thanks Gary. Yeah, moving :cljsbuild to the :dev profile works. I still
have to manually run cljsbuild though, which is annoying on my local
machine and I suspect it would break things like deploying to Heroku or
Cloud Foundry. So this will do for now but I'm still looking for a better
solution in the long run.
