Request the addition of Jinnish language

Thanks! But would it be zh-hant or cjy-hant as the fallback language for cjy? When we talk about fallback, it seems to me that we refer to another language, instead of a variant in the same language. I'm a little bit confused.

It always will fall this way: cjy -> cjy-hant -> zh-hant, so when a translation doesn't exits will use translation from the fallback language (when it's ready to be added to mediawiki).
