Support for Japanese

[breandan]

AceJump seems to have a bunch of Japanese users. It would be nice to offer support for Japanese input methods for text search in addition to #314. To implement this, we will need a library a library that can convert Japanese characters to ASCII, e.g.:

• https://github.com/nicolas-raoul/jakaroma
• https://github.com/andree-surya/moji4j
• https://github.com/jikyo/romaji4j
• https://github.com/bernd32/romaji-henkan

Alternatively, it may be possible to use a library that supports translating arbitrary Unicode to ASCII:

• https://github.com/anyascii/anyascii
• https://github.com/jirutka/unidecode
