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.

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.
