Solved annoyance in OSX warp cursor. The former used CGPostMouseEvent call

behaves very unpredictable (ask google) and seems to clear pending events
as well (fly mode, shift event dissappears).

The now used call, CGWarpMouseCursorPosition, creates no event so it has
to be combined with updating mouse cursor location in ghostwinlay.c
