[translations] zh-hant vs. zh-tw

[charles chuang]

Dear all,

There was an issue reported in Chinese support site about zh-hant
problem with Gallery2 module. He changed the locale setting form
zh-hant to zh-tw, and the Drupal/Gallery2 worked properly.
(http://tw-drupal.info/node/301)

I don't know why we use zh-hant(zh-hants for simplified Chinese)? The
zh-tw (zh-cn) is more popular in most programs.


sincerely,
Charles
