Added direct support for wheel encoders (Arduino Uno)
...
Added support for wheel encoder counting directly on the main Arduino board.
This allows connecting wheel encoders directly to the Arduino board,
without the need for any additional wheel encoder counter equipment.
For speed, the code is directly addressing the specific Atmega328p ports and interrupts, making this implementation Atmega328p (Arduino Uno) dependent.
It should be easy to adapt for other boards/AVR chips though.

Bugfix - removed reset wind-up fix
...
Removed the reset windup prevention code, as the old code already
took care of that by only incrementing Ierror when output was not being clamped.

Bugfix: added resetPID() call in RESET_ENCODERS statement,
...
to ensure that PID gets reset when encoders get reset.

Enhanced PID algorithm
...
Enhanced PID algorithm based on the series of blog posts at http://brettbeauregard.com/blog/2011/04/improving-the-beginners-pid-introduction/
Specifically:
1. Avoid derivative kickback - http://brettbeauregard.com/blog/2011/04/improving-the-beginner%E2%80%99s-pid-derivative-kick/
2. Allow smooth on-the-fly tuning changes - http://brettbeauregard.com/blog/2011/04/improving-the-beginner%E2%80%99s-pid-tuning-changes/
3. Reset windup mitigation - http://brettbeauregard.com/blog/2011/04/improving-the-beginner%E2%80%99s-pid-reset-windup/
4. Bumpless initialization - http://brettbeauregard.com/blog/2011/04/improving-the-beginner%E2%80%99s-pid-initialization/
