Title: Methods to access battery backed RAM

Submitting the addition of two methods, readMemory and writeMemory, for consideration. The methods allow a sketch to make use of the battery backed RAM on the DS1307. I've tested on Arduino 1.0 and V23 on OSX 10.6 against the Adafruit DS1307 breakout board on an Arduino Uno.
