Subject: [PATCH 2/3] Changed to make it work on ESP-01 boards (on ESP-01 pin
 cannot be checked at setup as its only available pins, gpio0 and gpio2, are
 shared with the bootloader) - moved triggering of configuration portal into
 Arduino's loop() function - changed pin from 4 to 0 (and made it 
 #define-able)
