flag for config change

[tzapu]

why does wifimanager not set the flag for saving the config internally? it would be much easier if we could do, after the autoconnect, if (wifiManager.configChanged()) { do stuff }

This was one of the first things I ran into when I started using WiFiManager. I concur, it would be a lot more handy if the callbacks were simply replaced with flags.
