[texworks] Simplified Chinese translation for TeXworks

[Arthur Reutenauer]

	Hello Yinhe,

  Thank you for the translation.  Independently of the installation
issues, may I suggest you use "zh-hans" as a tag for Simplified Chinese,
instead of zh_cn?  It is the recommended tag according to RFC 4646,
which describes Simplified Chinese better than zh_cn.  'Hans' is the ISO
15924 script code for Simplified Chinese (as a writing system);
Traditional Chinese is 'Hant'.
