Is This Café Wi‑Fi Safe to Use? "cafe-wifi-okawari" Now Includes an Offline Network Check

I've added a network check to "cafe-wifi-okawari", the Mac tool that automatically reconnects you when your free café Wi‑Fi session times out.
Staying connected is convenient, but most free café Wi‑Fi is not encrypted. If someone on the same Wi‑Fi pretends to be the router, or your Mac's settings leave it open to others on the network, you normally have no way of noticing. So the tool now looks at the Wi‑Fi you're connected to and your Mac's settings every 10 seconds, and lets you know in the menu bar only when there are warning signs.
