[PATCH] Make it easy to decline resolv.conf updates

[Daniel Kahn Gillmor]

There are situations where the user wants to use the routing
information offered by the VPN, but does not want to use the DNS
recommendations.

In this case, it'd be nice to be able to tell vpnc this preference.

With this change, a vpnc configfile line should do the right thing:

      Script /usr/share/vpnc-scripts/vpnc-script --no-update-resolv.conf
