Title: Normalizer ja

Add a normalizer for Japanese:
* Use `normalize_ja()` to get a consistent corpus before further processing.
* Function below `converters` namespace can be used to perform several conversion (ex: fullwidth to halfwidth characters).

Everything is thoroughly tested, but we should write tests for helper functions in `lib/natural/util/utils.js`.
