Handle running the install script over an existing installation (as the script already did before branching to test-wireguard), providing:
- Update, downloads latest scripts from git repo
- Repair, reinstall PiVPN while keeping existing settings
- Reconfigure, start over overwriting the existing settings
Tag iptables rules as an attempt to make sure that the uninstall script only removes PiVPN rules
Change the armv6l installation to reflect the split of WireGuard snapshots into wireguard-linux-compat and wireguard-tools
