WordCount and Summary support CJK Language
* add global `hasCJKLanguage` flag, if true, turn on auto-detecting CJKLanguage * add `isCJKLanguage` frontmatter to force specify whether is CJKLanguage or not * For .Summary: If isCJKLanguage is true, use the runes as basis for truncation, else keep as today. * For WordCount: If isCJKLanguage is true, use the runes as basis for calculation, else keep as today. * Unexport RuneCount Fixes #1377
