compatible with webpack 2

The uglify process of building project in production environment is very time consuming. It could take up to 70% of the build time. FastUglifyJsPlugin have multi-process and cache feature comparing to webpack's UglifyJsPlugin. Multi-process can utilize multicore cpu's caculation capability. Cache can minimize the need to complie code. Below is a set of performance testing data. FastUglifyJsPlugin has a way better performace.

|plugin|time| |——|———| |webpack.optimize.UglifyJsPlugin|7.4 min| |FastUglifyJsPlugin without cache|4.45 min| |FastUglifyJsPlugin with cache|36 s|

    },
    // set debug as true to output detail cache information           
    debug: true,
    // enable cache by default to improve uglify performance. set false to turn it off
    cache: false,
    // root directory is the default cache path. it can be configured by following setting
    cacheFolder: path.resolve(__dirname, '.otherFolder'),
    // num of worker process default ,os.cpus().length
