Added pinyin to all words - 在所有单词中添加了拼音

[MikeTheSnowman]

There are some non-Chinese speakers who would also benefit from this list. To help those people (and my self), I've added the pinyin to all of the vocabulary words.

有些不讲中文的人也会从这份名单中受益。 为了帮助这些人（和我自己），我在所有词汇中都添加了拼音。 请原谅我的中文语法不好，因为我使用的是Google翻译。
