dev mode? #126
Description
It's pretty slow to develop having to compile every run. Particularly because we keep increasing the number of steps.
I think we should have player.html use the coffeescript files directly (using coffee-script.js to compile it on the fly).
Consolation prize would be to have a dev-compile target that just translates and concats *.coffee -> .js.
(the biggest slowdown seems to be starting the damn closure .jar every time.)
