    modules/input/gtkimcontextime.c: Move to set_client_widget
    
    The imcontext internals have been changed to use set_client_widget
    instead of set_client_window in order to remove API dependency on
    GdkWindow.  Update the Windows IME support so that the code will
    continue to build and work.
