Change Chinese locale mappings for Flies integration

The Chinese locale codes on translate.jboss.org (zh-CN-Hans and zh-TW-Hant) were basically wrong, due to a bug in Flies 1.0. Scripts like Han Simplified and Han Traditional should actually come before country codes, so zh-Hans-CN and zh-Hant-TW would be better. On translate.jboss.org, these codes have now been replaced by zh-Hans and zh-Hant, which is better still because each of these scripts is used in more than one country.

I have already imported the affected translations again, but the locale mappings in flies.xml will need to be updated for future pushes. The github pull request is forthcoming...
