* Update translations
Adds German and Simplified Chinese and credits to the README
* Add warning when changing language without NitroFS
* Add separate plural and non-plural strings
* Add hu-HU, it-IT, update other translations
Also adds a few missing letters to the font
* Update translator credits
Kanji are from k6x8 from littlelimit.net, so added that to the credits (I hope I credited that right), the rest are from nds-bootstrap with minor edits (and more major edits to Arabic)
Was informed that the 3DS actually was translated to Russian and this it's worthwhile to put Cyrillic in the font for GM9, so updating this to match the update to GM9's font
