Implement more quest related nodes into sectors

[Simarilius-uk]

Asked what other than the splines would be helpful for quest modding, got this response: if you want to make something like a shop, you'll need an interior area nodes, community, population spawner nodes if you're working on a quest, you'll need trigger areas, guard areas, and also communities and population spawners

believe they should be fairly simple to do, just boxes/points that could be done via empties. Should consider how we export the info if modded/added for them

Someone else is welcome to pick this up, will do it myself at some point if no one does.
