    Add setting to disable the pyatspi GIL idle handler
    
    This change is made in response to
    http://bugzilla.gnome.org/show_bug.cgi?id=576954 where is appears
    as though the GIL idle handler in pyatspi is causing consumers of
    pyatspi (e.g., Orca and accerciser) to start consuming 100% of a
    CPU when the machine is idle.  We're pretty sure the GIL handler
    is not necessary, so this change gets rid of it for the 2.27.1
    development build of Orca.  If we see that users notice strange
    lock ups, however, we may need to change things back.
