DXF: Fix export of wireframe as 3D DXF.

Browse Source 
Before this commit, polylines got flattened but all other entities
got exported with the proper Z coordinate. After this commit, all
entities are exported with proper Z coordinate.

Also, instead of exporting LWPOLYLINE (2d only), POLYLINE (2d/3d)
is exported; as a bonus it is more compatible with 3rd party
software, since it is older.
