Issues #71 (script names) and #72 (language names)

Note: the change from a generic script name (`Chinese`) to a specific script ID (`Hant` = Traditional Chinese characters, `Hans` = Simplified Chinese characters, `Jpan` = Japanese characters, etc.) is technically a BC break.

However, it is unlikely that anyone would be using the previous definitions, as they don't really work for scenarios where identifying scripts is important.
