I18n support

Expected

I18n supported, Posts written in both English and Japanese are properly shown and markup.

This will increase non-Japanese readers.

When writing posts, writer can choose a language and language tag (e.g. lang:ja / lang:en) is automatically added.

Actual

Only Japanese posts are supported, though hreflang is already done.

How to achieve

1. Add lang in frontmatter and enable one on CMS (Select element will be suited).
2. Switch hreflang, lang, dateformat and all other related markups.
3. Also add language tag in tags.
4. Don't forget to add lang to old posts.
