- Split DirectInput keyboard handling into a separate file and class. I also

switched it to buffered input, and the pause key seems to be properly
  cooked, so I don't need to look for it with WM_KEYDOWN/UP. Tab doesn't
  need to be special-cased either, because buffered input never passes on
  the Tab key when you press Alt+Tab. I have no idea why I special-cased
  Num Lock, but it seems to be working fine. By setting the exclusive mode
  to background, I can also avoid special code for releasing all keys when
  the window loses focus, because I'll still receive those events while the
  window is in the background.
