Update translation .po files for puavo-client-updater-applet.
No network manager functionality when on webkiosk mode.
Put restrictions into policykit rules, and also suppress
the nm-applet from starting.
I think we can show puavo-client-updater-applet even when
automatic updates are true (it should be able to show
what is happening with automatic updates).
The applet starts up for puavolocaladmins, though,
and they can interfere with updates.
