Two Factor Pebble

Google two factor authentication running on a Pebble Watch, based on the Arduino version. It implements RFC-6238, "TOTP: Time-Based One-Time Password Algorithm" with a version of the SHA1 hash copied from an arduino library. The bargraph at the bottom shows how much longer the code is valid and updates with a new code every thirty seconds.
