add doom, disable warnings as errors, massive speedups in the fat32 driver, HAL_KEYBOARD Poll now returns the key and added IsKeyDown used by GetAsyncKeyState, slight upgrade in hal_main drain and pray, more accurate QueryTicks and by that GetTickCount, add GetTickCount64, boot.ini now dictates what executable should init launch, not the kernel, LaunchUserProcess in kmain.c now takes an argument, rearrange syscall numbers, add SysKbIsKeyDown syscall, use include windows.h over manual definitions, add fictional win32 api ClearConsoleScreenBuffer and real FlushConsoleInputBuffer and a clear command to the shell, print exit codes as signed int, StretchDIBits now can stretch, runa.bat now gives 256 MB.

## faq
Q: Why?
A: Why not?
A: Learning. Fun.
Q: Does it run Doom?
