  Basic ESP8266 MQTT example

  It connects to an MQTT server then:
-  - publishes "hello world" to the topic "outTopic"
+  - publishes "hello world" to the topic "outTopic" every two seconds
   - subscribes to the topic "inTopic", printing out any messages
     it receives. NB - it assumes the received payloads are strings not binary
-  - If the first character of the topic "inTopic" is an 1, switch ON the ESP Led, else switch it off
+  - If the first character of the topic "inTopic" is an 1, switch ON the ESP Led,
+    else switch it off
 
  It will reconnect to the server if the connection is lost using a blocking
  reconnect function. See the 'mqtt_reconnect_nonblocking' example for how to
  achieve the same result without blocking the main loop.
 
- To install the ESP8266 board
- Install Arduino 1.6.4+ (tested with Arduino 1.6.5)
- json file from https://github.com/arduino/Arduino/wiki/Unofficial-list-of-3rd-party-boards-support-urls added in "File -> Preferences -> Additional Boards Manager URLs"
- Open the "Tools -> Board -> Board Manager" and click install for the ESP8266"
- Select your ESP8266 in "Tools -> Board"
+ To install the ESP8266 board, (using Arduino 1.6.4+):
+  - Add the following 3rd party board manager under "File -> Preferences -> Additional Boards Manager URLs":
+       http://arduino.esp8266.com/stable/package_esp8266com_index.json
+  - Open the "Tools -> Board -> Board Manager" and click install for the ESP8266"
+  - Select your ESP8266 in "Tools -> Board"
