Make non-interactive map elements unobstructive.

This makes most of the lines and polygons on the map non-interactive so
they don't capture mouse events, and also makes the culling exclusion
zones unfilled so they don't obscure real map objects in dense areas.

Fixes https://github.com/dcs-liberation/dcs_liberation/issues/1217
