[update_2.1.2] Supports the Japanese language (Eng)

Hello,

This update is for supporting the Japanese language.

If the language setting on your phone is Japanese, you can see menus in Japanese.

Regarding an online Bible, there is JCB (Japanese Contemporary Bible) version in the Bibllica and I scripted to open it.

However I don't know Japanese, and all the words were translated by online dictionaries.

Please let me know if there is anything wrong!
