ESP8266 Web Server to storing ap config to EEPROM

ESP8266 Web Server to storing ap config to EEPROM.

Original by chriscook8 from esp8266.com I just modified to use ESP8266WebServer library for easy to handle the http request.

This is sample code not yet complete.

Todo

  • when Wifi connected need to close the softAP.
