Added Chinese support (Pinyin)

[franmomu]

I just cloned #158, rebased and squash the commits

[florianeckerstorfer]

Since you basically copied the lost from the mentioned script I have to ask what is the license of that code? Or is this list publicly available?

[franmomu]

It is in the commit's message: a3a2f5d:

Based on jifei's PHP class available at: https://github.com/jifei/Pinyin/blob/master/Pinyin.php

(Not sure if it is what you meant)

[florianeckerstorfer]

What I meant was what is the license of the project? Are we allowed to use the code from this other project here?

[franmomu]

I've just written an email to @jifei asking, if there is no answer we could use maybe the chars.csv here

[florianeckerstorfer]

Thanks, ping me if you've got a response.

@florianeckerstorfer I've just got a response:

Glad to receive your letter.The code is long time no maintenance, you can use it, it is best to indicate the source.

So, is it enough with the commit comment? or should I add the repository url somewhere else? (I can only think of the SlugifyTest) .

[florianeckerstorfer]

@franmomu I will add a note to the README. Thanks for the PR.

[franmomu]

You're welcome!

@franmomu thanks for cloning #158, not sure what I did wrong in the first place, but I'm glad you made it work. Thanks.
