Add Time Support (server + manual setup), only used for ESP32 FS currently as ESP8266 SPIFFS does not support Time, need to wait for LittleFS may be ? Add DHT support Add Pin reset support Add Base for Display Add libraries for new supported features Add /config handle as shortcut for [ESP420]plain to be used in embedded page Code refactoring for defines, use less Define as switches but more define as values for switches Clean warnings Lot of small bug fixes Add docs for [ESPXXX] commands
