Title: Issue159

this is the old modification of DXF Tessellation that will let self-intersecting polygons get imported, but display a two-line warning. It can help people figure out where there polygons are 'non-simple'.

It addresses issue #159

If the new "issue11 2" branch is pulled I will update the test code for guicgalpngtest
