Export of filament statistics into G-code for multi-material prints

Browse source 
has been rewritten to be easier to parse.

Old format
; filament used = 19248.8mm (46.3cm3)
; filament used = 57.4
; filament cost = 1.5
; filament used = 8007.6mm (19.3cm3)
; filament used = 23.9
; filament cost = 0.6
; filament used = 0.0mm (0.0cm3)
; filament used = 0.0mm (0.0cm3)
; filament used = 0.0mm (0.0cm3)
; total filament cost = 2.1

New format
; filament used [mm] = 1600.7,1600.7,1600.7,1600.7,1600.7
; filament used [cm3] = 3.9,3.9,3.9,3.9,3.9
; filament used [g] = 4.8,4.8,4.8,4.8,4.8
; filament cost = 1.5,1.5,1.5,1.5,1.5
; total filament used [g] = 24.0
; total filament cost = 7.5

Where the non-printing extruders are filled in with zeros, and
the trailing non-printing extruders are not exported.

; filament used [g]
and
; filament cost
are only printed if non zero (material density and cost are defined)
