Subject: client: Add support for displaying VPN connections

Show a list of VPN connections known to the VPN daemon.

Also allow D-Bus path names to start with numbers, as it is fine with
the D-Bus library to define such path names. Fix up help command
pretty-printing as the VPN command is slightly longer.
