Firmware for ESP8266 used as SD card logger using Arduino core version

Development version:
Arduino ide 1.8.0 with git from ESP8266

Using pluggin IDE
Any files on SPIFFS can be called on web interface without having the path hard coded, this give more flexibility, favicon.ico is a good example of it.
So UI is kind of separated from FW which allow easier modifications. For this a light file manager is available in extra settings page, it allows to upload/download/delete files. Because SPIFFS is flat filesystem, no directory management is necessary, so it is very simple.
