Add mirrors in China

Well, at first I just wanted to create a mirror on mirror.anthonos.org , since this Linux-based system has added OpenRA into its deb repo and resource package downloading issues often occur in China (behind the GFW ). 

And then I found that the rsync of these extra mirrors synced everything from the AnthonOS mirror ... That's why there are so many other mirrors now.

Mirrors http://mirrors.scie.in/anthon/ and http://mirrors.hust.edu.cn/anthon/ seems to be delaying a bit so files from these mirrors are still 404s now.
