Marlin Localization For Chinese Simplification

Marlin Firmware Localization For Chinese Simplification

Long time ago, I tweeted Marlin firmware (@MarlinFirmware) to merge my modification for better Chinese Simplification supported. But it looked like those guys had no time to apply it. Until now, the newest released Marlin firmware's Chinese localization sucks.

Now I list my code here. Hope it's helpful for others.
