Calculate extrusion width %s as a function of nozzle width, not layer height (#1578)

Browse Source 
* Calculate extrusion width %s as a function of nozzle width, not layer height

* handled more width conversions

* more missing percent handling

* even more missed percent handling

* even more more extrusion % handling

* some fixes
