Add support for enhancing the precision of endstop switches by also
inspecting the phase of the stepper motor when the endstop triggers.

Rework the code so that the kinematic class (currently just
cartesian.py) has more control over the homing process.

Only skip acceleration between moves if both moves perform a similar
amount of extrusion. This ensures the extruder has sufficient time to
accelerate to and from each extrude move.

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.

Explicitly check for when the move_queue is empty and only call
move.calc_junction() when there is a previous move. This avoids the
need to create a dummy "sentinal" move object and it simplifies the
code.

Remove the lookahead.py file and move its code directly into
toolhead.py. The MoveQueue() class is small and tightly coupled to
the toolhead code.
