Add a config option to define an amount of additional filament to feed
into the extruder during acceleration and deceleration of the
extruder. This can help ensure plastic is deposited in the correct
places during a print.

Allow the owner of the stepper object to cacluate the maximum step
jerk velocity. This is used to ensure there is no communication error
between mcu and host.
Disable checking of jerk velocity for extruder stepper motors.

Create a new python file (extruder.py) to control the extruder heater
and stepper motors. This separates the extruder control logic from
the cartesian robot code - making it easier to customize both the
kinematic control of the robot as well as the extruder.
