title: Is there any way to tell angular-cli (for angular 2) to generate minified version of css?
body: <p>As the title says, when I run "ng serve" angular-cli generates normal css whereas I expect to get the minified version.
  Is there any specific setting to use for angular-cli-build, or some additional plugin to install and use?</p>
  
  <p>This is my angular-cli-build.js</p>
  
  <pre><code>var Angular2App = require('angular-cli/lib/broccoli/angular2-app');
  
  
  module.exports = function(defaults) {
    return new Angular2App(defaults, {
      vendorNpmFiles: [
        'systemjs/dist/system-polyfills.js',
        'systemjs/dist/system.src.js',
        'zone.js/dist/**/*.+(js|js.map)',
        'es6-shim/es6-shim.js',
        'reflect-metadata/**/*.+(ts|js|js.map)',
        'rxjs/**/*.+(js|js.map)',
        '@angular/**/*.+(js|js.map)',
        'angular2-cookie/**/*.js'
      ]
    });
  };
  </code></pre>
