Default Kiosk Profiles and Kiosktool Support

For institutional deployment (e.g. schools, universities, companies, government offices) having lock down facilities is critical. KDE has excellent and extensive support for this which should be leveraged by providing a set of pre-defined profiles that can either be used out of the box ("Just Works") or used as a starting point for customizations. This would add great value to Kubuntu in these scenarios as it is often one of the primary requirements.
