Slicer bug in Relative Extrusion

A quite great bug found in slicing with Realtive Extrusion Distances active.

If it was just an view problem, nothing to blame for.

BUT: Printing via USB, LAN and SDCard will result the same. Cutted paths as in the preview, or if you prefer, extrusion hiccups.

Worst than that, no matter if in Absolute or Relative mode: GCode files created with Simplify3D won't print right with Smoothiboard.
Lack of retraction (nozzle lift in retraction works, but filament does not came back), Smoothieboard crash (memory dump clearly shown that too much G92 E0 repeated for no reason, causes memory leaks and subsequent board fault) until I found that reducing Planner value from 32 to 16, mitigates the problem.

You should really consider to support Smoothieware firmware and the GCode varianta it uses, as you've done with Sailfish.
