Adafruit_CharLCD/Adafruit_CharLCD.py: Pin change for Rev 2.0 Pi

[pdp7]

The RPi.GPIO actually does auto detect the Raspberry Pi revision. By switching to BOARD pin addressing instead of BCM, the code works ok on both the Rev 1 and Rev 2 Pi's.

we added a note to the tutorial and the code about the pin change - the cobbler has BCM pinout so we want to keep it with BCM :)
