Usage

In config file:

var WebpackBeforeBuildPlugin = require('before-build-webpack');
// ...
  module: {
    plugins: [
      new WebpackBeforeBuildPlugin(function(stats, callback) {
        // Do whatever you want...
        callback(); // don't call it if you do want to stop compilation
      }),
    ]
  },
// ...

OR (more power)

// ...
  module: {
    plugins: [
      new WebpackBeforeBuildPlugin(function(stats, callback) {
        // ...
      }, ['run', 'watch-run', 'done']), // will fire before build and after build
    ]
  },
// ...

You can use pre-v4 or v4 hook names (i.e. any of watch-run and watchRun)
