Initial WiFi Access Point will have unique name.
Device now will have automatic setup request popping up (captive portal), when connecting to it's WiFi (at least for Android devices).
Soft AP IP address changed to 8.8.8.8 due to previous change.
Configuration flow is changed in the way that will produce less errors:
- Initially, when device is in AP mode, only WiFi settings and device name are set;
- After that, it tries to connect to WiFi in parallel, and if error, it will allow to revise settings;
- After connecting to WiFi, MQTT can be set up;
- If MQTT setup is incorrect, it will be shown on info page;
- Info page allows to re-configure MQTT, or completely reset configuration.
Hiding passwords in input fields (were in plain text, bummer).
LED blinking is set up to represent current configuration status:
- 2 times per second: device is in Access Point mode;
- 1 time per second: WiFi configuration is done, but cannot connect to WiFi;
- 1 time per 2 seconds: WiFi is connected, but no connection to MQTT server (or MQTT configuration needed);
- constant light: device is working properly;
  - during this, short flash offs will indicate, that some beacon is found and data sent to MQTT server.
Introduced hard configuration reset. If something went terribly wrong, and there's no way to configure device (e.g. WiFi went down or changed password), you may reset configuration and return device to AP mode by resetting it by 5 consecutive restarts with less than 5 seconds in between.
