QXcbWindow requestWindowOrientation fix

commit 68cac318403df59ef861b632b3af15b4342d8c83
Author: Lauro Neto <lauro.neto@openbossa.org>

    Add requestWindowOrientation implementation for QXcbWindow
    
    QXcbWindow implements setOrientation in Maemo but the application
    has no way to request a new orientation as QPlatformWindow implements
    just a placeholder method.
