version 1.2.0 - npm run build - slowly！！！

[lzsheng]

从1.1.1版本升级至1.2.0版本后

运行官方browser-example的代码，执行npm start是很快的，但是在执行npm run build的时候，大概要构建2-3分钟。

在我自己的项目中（使用v1.1.1版本，构建时间大概是45s），但是升级了v1.2.0后等待超过10分钟依然不能构建成功！！！但是换回 v1.1.1 版本后，却能正常构建

请尽快解决这个问题～～辛苦啦

运行官方的browser-example，把版本降为1.1.1，速度明显比v1.2.0快很多！

@lzsheng what's your node version and OS?

[cwtuan]

Building browser-example consumes about 140s in both of v1.1.1 and v1.2 in my computer (Mac air, node v6.11.0)

[lzsheng]

nonde:7.2.1
macOS:10.12.4 (mbp 2016)

[lzsheng]

v1.2.0: building browser-example consumes about 114s
v1.1.1: building browser-example consumes about 12s

[cwtuan]

Currently, you could use v1.1 if you only need browser rendering.
v1.2 supports server rendering.

[lzsheng]

ok,thx!

There is a significant size difference in the builds between 1.1.1 and 1.2.0.

My locale loading goes something like this:

import intl from 'react-intl-universal';
import fi from './locales/fi';
import en from './locales/en';

const locales = {
  'fi-FI': fi,
  'en-US': en,
}
const locale = 'en-US';

const loadLocales = () => {
  intl.init({
    currentLocale: locale,
    locales,
  }).then(() => {
    //console.log("locales loaded");
  });
}

Building the package:
v1.1.1:
File sizes after gzip:
156.54 KB build/static/js/main.588b5386.js
2.21 KB build/static/css/main.aa3bb3e1.css

v1.2.0:
File sizes after gzip:
1003.92 KB (+847.34 KB) build/static/js/main.5580900c.js
2.21 KB build/static/css/main.aa3bb3e1.css

Checked the build with source-map-explorer and it does include locale data files for every language, not just the ones defined with the locales.

@lzsheng @Jorer
Please upgrade to v1.3.4 to fix build issue.
