Fixes to make the drivetrain work
More OBD work
Temporarily disabled on-board diagnostics.

See issue 5 for more information.
Added initial code to store the git revision at compile time and print it during robot startup
Improved version information
small version information improvement
Diminutive fix for revision metadata
Initial tuning of moving PID done. The constants will need to be re-tuned when the robot actually has weight on its wheels.
Added PWM channels and initial implementation of gates
Tuned PID (straight & rotate) with the robot on its wheels. Driving straight slightly overshoots and rotating slightly undershoots, but they do so predictably.

We might want to switch the drivetrain motors to coast mode and see if
that improves things.
Changed TimedTask from scheduleAtFixedRate() to schedule(). Fixes issue #6.
Pusher: Updated motor power constant based on testing
Added initial cow protector stuff
Added debugging stuff
Temporarily removed accelerometer. Clean this up later.
More cow protection work
Cow protection initial implementation done
More cow work
More cow zeroing stuff done
Updated cow positions for zero = shoot3
