* Description: Platform agnostic Qt wrapper class for controlling display
*              power save mode. The power save mode gets actually activated
*              only on Symbian environment; in other environments the provided
*              functions do nothing.
*              The use of Symbian display power save API has been wrapped with
*              client-server pair because HbDeviceDialogs don't have enough
*              capabilities to call that API directly.
