Title: Stepsperunit parameters

This is what I consider a better way of configuring axis scaling and extruder parameters.

I have left the hard-coded magic numbers because I still dont know which specific parameters where used to obtain those values. Please consider expressing all those configurations by defining the following attributes, so that they are easier to tweak/understand:

* steps_per_revolution
* microstepping
* belt_pitch
* pulley_teeth
* extruder_gears_ratio
* bolt_diameter
* z_thread_distance
