Multicolor mixing extruders

Definition

Color mixing from multiple extruders on single hotend, currently might no full color flow from CAD tool export AMF -> slicer -> gcode.
But at least we can try to based on tool change gcode + repetier fw mix extruder implemention for some profiled color printing[read reference 3]. Or we can tune the slicer anyway (might be a hardway)
Color mixing works on ref[2] as proved. But the setting is just a theory, not tested on 5 or 6 extruders yet.

Reference

For RAMPS 1.4 + Repetier Firmware 0.92

based on AUX-1 & AUX-2 + AUX-4
