Add new translations to zh-rCN locale

Also add prefix "issue" to occurrences of "label"

This is for differentiating between the terms "label"
(of issues), and "tag" (of commits), both of which are
translated to "标签" in Chinese, introducing a clash.
Hence, "labels" are prefixed to avoid confusion.

Closes pull request #207
