OneWireNoResistor

A slight update of the popular Arduino 1-wire library for AVR-based arduinos that...

1. Eliminates the need for the extra pull-up resistor (the big show)

2. Adds a busFail() function to let you test for a shorted bus

3. Slight updates to comments and formating

New branch is for the ESP8266 and was contributed by Antoine here..
