Refactroing: Get rid of utils methods.

Made private: scaleFace(Mesh3D mesh, Face3D face, float scale)
Removed: extrudeFace(Mesh3D mesh, Face3D face, float scale,
           float amount, boolean remove)
This special version of face extrusion was used by the ported cube
creator only and had too many parameters anyway.
