Correct convex hull in one-at-a-time mode

Browse Source 
The new convex hull should be the hull with head and fans intersected with the mirrored head and fans. This is because it can determine the correct order to print the objects without getting the fans in the way as much as possible.

Contributes to issue CURA-260.
