L10n for Git in Chinese begins

With the release of v1.7.9 or some earlier , Git is multilingual. I select some typical git commands and translated into Chinese, works nice.

- git status (in c)
- git stash (in bash)

Now I create a repo in Github hosting the po file (zh_cn.po) for git.

- repo: https://github.com/gotgit/git-l10n-zh-cn/
- file: https://github.com/gotgit/git-l10n-zh-cn/blob/master/zh_cn.po

Any help is appreciated, and will contribute here after 100% completed.
