Very much appreciated, thank you. I'll add it with the next release.

The flag for the chinese language is already present, actually, but it only works when changing the id to 'zh', the ISO 639-1 code for chinese. I'll rename it to that for the release, too, just wanted to let people know who wish to use it before that.
