Refactoring of adaptive cubic / support cubic:

Browse Source 
1) Octree is built directly from the triangle mesh by checking
   overlap of a triangle with an octree cell. This shall produce
   a tighter octree with less dense cells.
2) The same method is used for both the adaptive / support cubic infill,
   where for the support cubic infill the non-overhang triangles are
   ignored.
The AABB tree is no more used.
3) Optimized extraction of continuous infill lines in O(1) instead of O(n^2)
