conf.json issues

[JAndrassy]

There are issues with conf.json. It's accessible with url and it gets lost after SPIFFS flashing. I think it should not be a SPIFFS file. Maybe the parameters could be saved with EEPROM library or there is a Wifi config mentioned in the flash layout diagram in Filesystem doc, but I can't found anything esp8255 core related about it.

Per the discussion in #25 , browsing to http://192.168.xx.yy/config.json for the present device from any other device on the same network returns {"ssid":"your_ssid_name","password":"your_formerly_secret_password"} (with the actual unencrypted data).
