59c4984ed6 Deprecated internal filter of PID controller (#746) 
This was replaced with an external LinearDigitalFilter.

7867e906e9 NidecBrushless: Have disable() call PWM.setDisabled(). (#763) 
This provides a way to stop motor operation even if the DIO is disconnected.

Also change Set() to enable the PWM instead of having the constructor do it.

Provide an explicit Enable() call to re-enable after Disable() is called.
This is different from the other motor controllers (which automatically
re-enable when Set() is called) due to the dual-wiring of this motor
controller.

Motor safety results in disabling the motor only until the next Set() call.

26a36779a6 Performed cleanup of Timer's free functions (#776) 
* GetClock() is now officially deprecated since its comment already informally
  did so and the function just forwards to Timer::GetFPGATimestamp().
* The declaration of GetPPCTimestamp() is missing a definition and has been
  removed.
* std::this_thread::sleep_for() returns immediately when given a negative
  duration, so the check for that was removed from Wait().

34c44b7ae9 Improved Drive docs and fix implementation bugs (#774) 
I also found some inconsistencies in MecanumDrive and KilloughDrive and fixed
them.

Drive now uses the NED axes convention. Therefore, the positive X axis points
ahead, the positive Y axis points to the right, and the positive Z axis points
down.

Translation in X assumes forward is positive. Translation in Y assumes right is
positive. Rotation rate assumes clockwise is positive. Angles are measured
clockwise from the positive X axis.

Based on the angle origin convention, DrivePolar() for both Mecanum and Killough
needed the normalization removed, sine used to compute the Y component, and
cosine used to compute the X component.

The vector rotation done in DriveCartesian() needs to rotate by a negative angle
instead of positive to undo the robot's rotation. RobotDrive assumed a clockwise
angle and sensors returned counter-clockwise angles, which is why it used a
positive angle for rotation.

5c659fdcdf Deprecated PIDController::SetTolerance() (#764) 
PIDController::SetPercentTolerance() behaves identically to it, so removing
SetTolerance() leaves one obvious way to do absolute or percent tolerance.
