Releases v1.1.0 to add support to ESP32/ESP8266

### Releases v1.1.0

1. Add support to ESP32 and ESP8266 using EEPROM, SPIFFS or LittleFS
2. Add many complex MQTT Examples to demonstrate how to use the dynamic parameters, entered via Config Portal, to connect to **ThingStream MQTT Server** at `mqtt.thingstream.io`.

 Enter your credentials (Blynk Servers/Tokens and Port). If you prefer static IP, input it (for example `192.168.2.220`) in the corresponding field. Otherwise, just leave it `blank` or `nothing` to use auto IP assigned by DHCP server.

 Then click `Save`. After the  board auto-restarted, you will see if it's connected to your Blynk server successfully as in  the following picture:
