Update zh_CN.lang

Few changes. The previous guy is green on github, so I fixed some existed problems.
However I am not sure how shall I call the custard. In the game it was made from suggar and milk in the vat. The old translation "奶油冻" means a kind of pudding-like food made by milk, eggs and sugar in chinese. While another one "牛奶沙司"  means milk sauce. Maybe the latter is beterr. :P
Self-talking: While Im testing these machines in game for the next localization, I havent notice ViKaleidoscope’s message on the chatting window, that may lead to his departure from my group (Pity :( ) Sorry to bother u.
