#7 Japanese translation updated

[Tadashi Jokagi]

I Japanese translation updated.
Current translation file is supporting only Encoding of
EUC-JP.
I added encoding of UTF-8 this time, and added one
element to $langueTranslated.
-4=>"German", 5=>"Japanese", 6=>"Italian",
+4=>"German", 5=>"Japanese(EUC-JP)", 6=>"Italian",
7=>"Croatian", 8=>"Brazilian portuguese",
9=>"Netherlands",
10=>"Spanish", 11=>"Danish", 12=>"Chinese traditional",
-13=>"Chinese simplified");
+13=>"Chinese simplified", 14=>"Japanese(UTF-8)");

An official Japanese translator's Rui checked this
translation and idea.
