Security Fix for WiFi Login Pages

[Federico Capoano]

Hi everyone,

I was informed only today by a partner of the OpenWISP Community that the polyfill.io domain was unmaintained and got in the wrong hands. 

The WiFi Login Pages application uses that old domain for loading polyfill and ensuring compatibility with old browsers.

Fortunately, the domain has been blocked by internet authorities, but it's nonetheless advised to upgrade.
