partially update of the Chinese translation (zh-Hans)

[brucekomike]

Hello. I am a native Chinese speaker. I've add some new translation and updated some of existing translation since they were written in zh-Hant (aka zh-TW, I want politcs to fade).

Then, there are some entry I have not get their meaning:

• Page ( Does this just mean a page on a book? and I've noticed that somewhere says it means passage.)
• Ham (it's a type that articles can be marked as. but apart from a spam, what is a Ham?)

Further translation will be there.
