World|BSP Builder: Only produce Segments for the half-edges of map line sides
In the case where an edge is produced automatically when partitioning space into convex subspaces a line segment is unnecessary (these will never be drawn as (implicitly) they have no surfaces).
The geometry/topology information is all that is needed in this case, which, is now modeled with half-edges.
