* Swap Google Closure Compiler for Babili
* Browser compiler, minified by Babili
* Use Babel to transform, not just to minify; add process.env.TRANSFORM to disable transforming if we only want to minify. Unfortunately several browser tests fail when transformed . . .
* Move `super()` calls so that the Babel-transformed browser compiler passes all the browser tests (in Node, at least)
* Updated browser build
* Update browser tests
