[jhc] Jhc User's Manual has been translated to Japanese.

Hi, all. Jhc User's Manual has been translated to Japanese. You can read it on http://metasepi.masterq.net/posts/2013-01-12-jhc_manual_ja.html. And it's translated with po4a http://po4a.alioth.debian.org/. (See attached patch.) I think this patch will make easy to translate it with the other language. I'm so happy if jhc repo merges the patch, and I will update ja.po file while jhc is released. Best regards, -- Kiwamu Okabe
