Change the config file so that the delta arm length is specified
per-tower. This makes it possible to support advanced calibration.

Rename the thermistor_type and thermistor_pin config variables to
sensor_type and sensor_pin. This is in preparation for support of
sensors beyond thermistors.

Not all hardware has PWM support and there is no compelling reason to
use hardware PWM for fans. Change the default to use software PWM.

There's no reason for the user to specify position_max - it can be
inferred on deltas from the endstop positions.

Some XY moves at the extreme end of the build envelope could cause
excessive axis stepper movement. Check for any moves that could
possibly result in a stepper movement of more than 3 times the XY
movement and cap the move's acceleration and speed.

Instead of requiring the user enter velocity and accel parameters for
extrude only moves, calculate sane defaults from the printer's maximum
velocity and accel.

Be more clear on which parameters have defaults and which parameters
must be specified in the config.

On a delta printer, z moves require the mcu to support the greatest
number of steps per second. However, z moves are rare, so it makes
sense to limit the velocity of z moves separately from the velocity of
normal xy moves.

Change the config file so the maximum accel and velocity are specified
in the "printer" section instead of the individual "stepper" sections.
The underlying code limits the velocity and accel of the toolhead
relative to the print object, so it makes sense to configure the
system that was as well.
