China localization

I am a native Chinese (simplified) speaker and has used CakePHP for a while. I just wrote localization for China, including:

* Simplified Chinese LC_MESSAGES (hand translated)
* Simplified Chinese LC_TIME (copid from glibc)
* Validation rules for Peoples Republic of China (mainland), including phone number, zipcode and ID number, along with test cases

I am willing to contribute these things to CakePHP, in whatever free license (looks like it is currently MIT).

BTW, I've added my own name in the validation class & test case, but it seems all other files only include 'Copyright CakePHP team'. Tell me if there is any problem, or just remove my own copyright lines (it's OK).
