Languages

By creating a langname_local directory, admin can make our own string for langname. If I make a string in zh_cn_utf8_local, the user who use en, es, ko and etc. can't see the string. I don't know so many languages to patch many _local. So I have this idea.

Create a directory named local_global and construct it just like *_local. In get_string(), read *_local first. If the string is absent, then read local_global, then normal langpack.

The following is the patch:
