[feature] add button on webapp to reset wifi configuration #19
Description
Currently, the stored wifi configuration can only be reset by uncommenting the line "wifiManager.resetSettings()" in wordclock_esp8266.ino and running the program once. After that the line need to be commented again and the code need to be flashed a second time on the esp.
The idea with this feature request is to add a button in dashboard which calls the endpoint /resetWifi to erase the wifi configuration and restarts the esp.
