Added logging of more data, made PID work properly, added MotorTest.

PID adjustments needed to be accumulated to have any effect.
Input to PID needed to be converted from rad/s to MotorDriver units based on
empirical measurement.
RobotMotion takes rad/s, moved constants into Robot, initial state into robot.
