Minimap improvements

[Noname]

Spawn points on the map is an easy addition, consider it done.
The radius of barrel explosions and boss abilities is something that will clutter the map if there are too many occurrences.
AFAIK the AI mesh is not an actual sceneprop, so I don't think there is an way to make them show on the map.

Thank you very much for clarification. Would it be possible to add some sort of scene prop (like the AI mesh) to model the maps in the map editor by hand? I'd volunteer to do so
