Win32 fixes. Fixed slightly off cursor positioning when using

absolute mouse_event().  Improved keyboard handling:  now using
keyboard layout of last foreground window when leaving server
so users can meaningfully choose the locale, moved dead key
handling into hook library so there should be no more race
conditions involving the keyboard dead key buffer, simplified
keyboard and cursor handling by using a full screen transparent
window when not using low level hooks, fixed error in restoring
buffered dead key when checking for dead keys.  This hopefully
fixes all known keyboard bugs on win32.
