Title: Switched from browserify to pure-cjs builder

Switched to [recast](https://github.com/benjamn/recast)-based own [pure-cjs](https://github.com/RReverser/pure-cjs) CommonJS builder which allows to save ~10% of minified+gzipped library size.

Current comparison table is following (used output of `grunt-compare-size`):
