Updating Firmata (to r62 of their repository).

Browse Source 
Changes include (according to Paul Stoffregen):
"1: Hardware abstraction layer to support Arduino Mega, Teensy and Sanguino.
2: Extended analog message, to facilitate using PWM and Servo above pin 15.
3: Capability queries (alpha), to allow automatic discovery of any board's features."
