Using atk_object_notify_state_change() instead of manually calling g_signal_emit_by_name() has the clear benefit that we don't emit by mistake an incorrect change of state, since we are forced to use values from the AtkState enum instead of raw strings.

We should change it in AXObjectCacheAtk.cpp to avoid further confusion.
