DXF-Exporter update
v1.27 - 2008.10.07 by migius
- exclude Stani's DXF-Library to extern module
- add "hidden mode" substitut: back-faces removal
- add support for mesh ->POLYFACE
- optimized code for "Flat" procedure
- modif FACE class for r12
- add mesh-polygon -> Bezier-curve converter (Yorik's code)
- add support for curves ->POLYLINEs
- add "3d-View to Flat" - geometry projection to XY-plane
