pivpn/scripts/update.sh
Orazio 823afa3fbb Improved dual VPN uninstallation, remove duplicate code/script
- Allow using 'pivpn vpn -u' to directly uninstall VPN 'vpn'
  - Also allow using 'pivpn -u' with two VPNs (will present a dialog).
  - During uninstall, ask which VPN to remove only if there are two VPNs
  - PiVPN git repo will be downloaded to '/usr/local/src/pivpn'. All scripts
    in /opt/pivpn, the main pivpn script and the bash completion file,
    are now just symbolic links. Resolves issue .
  - Remove unused call to updateWireGuard().
