[Kde-kiosk] temporary switching off kiosk restrictions via hotkey and special kiosk password [auf Viren überprüft]

[Reinhard Hennig]

Hi everyone !

We are planning to use a restricted KDE-desktop on linux for up to 12000 
users.
A useful feature for us might be to implement a temporary switching-off 
kiosk-restrictions.
This would mean, kiosk restriction can be switched off during a session 
using
a special hotkey that causes a popup window requesting a special "kiosk 
password" that might
be different from the systems root password.
After having finished  your work a special hotkey should reactivate the 
restrictions again.
This feature might be helpful for diagnostics because it enables a shell
for the administrator or developer if shell access is forbidden.
