style(all): Convert to es6 + standard

Code is functionally equivalent, but source has been moved to
es6/es2015 style, including es6 modules. babel is now used for
compiling.

BREAKING CHANGE: UMD output is no longer pre-generated

build/genfun.js and company are gone. Instead, CommonJS output
is generated from the ES6 sources and output to dist/, mirroring
the src/ tree. The files are separate, instead of concatenated.
