- 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 #695.
- Remove unused call to updateWireGuard().
- 'pivpn -up' pulls the latest scripts from github, however, as of now, its usefulness
is limited since usually a change in those scripts is a result of a change in the
installation process, and those changes can't be applied to an older installation.
