Changed Chinese Locale file name, Add GB2312 character set, fix ellipse resize error.

[Refactoring]

I am a Chinese, my English is not very good. My commits log using the Bing translation from Chinese into English. Hope it will not affect the description of the journal, your reading.

Thanks for all this! I split your request into multiples:

• Ellipse surface goes negative #271 for the ellipse bug
• Use correct Chinese language code #272 for the Chinese translation folder

About the GB2312 character set, do you have data with it that you could share for testing?

GB2312 DCM Test Data
Focus tag:
(0008,0080) Institution Name LO 1 测试医院
(0010,0010) Patient's Name PN 1 赵桂香


I wrote this test, do not know the appropriate or not?
