v1.10.5 using PROGMEM for strings

### Release v1.10.5

1. Using PROGMEM for strings in examples. Check [Example fixes #32](#32)
2. Using PROGMEM for HTML strings. Check [implement PROGMEM strings, alignment with ESP_WiFiManager_Lite #31](#31)
3. Default LittleFS for ESP8266 in examples
4. Improve `README.md` so that links can be used in other sites, such as `PIO`
5. Sync with `ESP_WiFiManager_Lite` v1.10.5
