VPN settings available though not installed

The NetworkManager plasmoid lets the user add and edit VPN connections even if the plugins are not installed. No error message is shown and the user would suggest that setting these option(s) is all he has to do to access a VPN. But he hast to install the plugin, too.

I can see two solutions:

1) Let the VPN-Tab available but show no settings but a notice that additional packages have to be installed.

2) Let the VPN-Taba available and as soon the user tries to set up a specific VPN derivate the needed package could be installed automatically (as for example the codec installation).
