Japanese translation

Hi Claudio,

I'm Ryuunosuke, who translated version 1.0 and 1.1 of the Infographic of Debian into Japanese.

Thanks for your great update of Infographic of Debian.
I've translated it into Japanese. This is a 1st draft of translation.
Please check them especially commit messages.

I couldn't find any instructions for translation policy.
So, I simply follow general procedure for translating SVG document.
1. generate PO template from from SVG file via po4a-gettextize
2. generate PO file from PO template file via msginit
3. translate PO file
4. generate Japanese-translated SVG file using translated PO file via po4a-translate

When I check the finally-generated file "infographic_debian.ja_JP.svg"
on my inkscape, I find some problems,
1. misfit string in box, unexpected line breaks
2. garbled words (missing font?)

We have same problems on 2012 for the translation of version 1.0 and 1.1.
At that time, you change the layout of the master SVG file and install fonts, if I correctly remember.

Awaiting your reply. Regards,
AYANOKOUZI, Ryuunosuke
