Update zh_CN.lang

1.Polish a lot.
2.Something is wrong with the display of text in game, I mean the 'Mending Circuit.name' and 'Thundering Circuit.name' in Creative tab.
3.The effects of Advanced Ice and Advanced Lava do affect the player himself, so once u equip them u will also get slowness or on fire. 
Last but not least, thx for making this mod. And call @Adaptivity
