Commented Unassigned: zh-CN translation issues [239]

Hi.es

I just check new zh-CN (Chineese) translations and found some issues:
* Too many empty keys at Account/Manage like in already fixed [#231](https://bugnet.codeplex.com/workitem/231)
* Some common entries for controls already live in SharedResources. For example: Password, PasswordRequiredErrorMessage, Remove, ConfirmPasswordMismatchErrorMessage, etc.

I understand that SharedResources file is not ideal, but this will make translator's work to be quite easier )))

PS:
Unfortunately, author the translation prefers to not be contacted. So I wrote this here.

Thanks.
Comments: Thanks, I will fix up those merge errors
