 rev. 12374 (reactos/subsys/win32k/ntuser/keyboard.c) broke csrss
 (ReadConsole, line input). i'm looking into it, but can't
 promise anything 
Sorry for breaking it, I've reversed my change for now. The change was
introduced because PuTTy would see both key down and key up as an input
event, so every letter you typed would be doubled. I'll find another way to
fix it.
