"Fixed" manual WinDOS window positioning
"Fixed" manual WinDOS window positioning

 When moving the window with the mouse, GetClientRect suddenly
 returned nonsense and sgui_window_move launched the window into
 lunar orbit. Now we don't adjust the position anymore and the
 move window function does not move the client rect but the entire
 window instead (boo hoo).
