Summary

SUMMARY: Content "Adds stair/footprint matched basements to some houses"

Purpose of change

@curstwist has been going around adding roofs to old house JSON maps and renovating them. These houses still do not have staircase matching to the basements. Eventually we want to eliminate the code that lets you teleport when you go down stairs, so we'll need to make staircases align. Plus, the old basements are just not that great.

Describe the solution

Adds matched basements to existing house plans. Also adds some useful nested maps like offices.

This adds a basic basement with randomized nested mapgen including a home office, a toilet, some bedrooms, a utility room, and a rec room / living room.

Describe alternatives you've considered

I don't have to get all up in the nested maps but I am bad at doing things quickly.

Testing

Final version, with rotation and monster spawns

Additional Context

I will make a follow-up PR with some more varied floorplans, at least an unfinished basement being used for storage. I'd like to add a basement that works as a secondary suite as well, but that's tough without the ability to modify the level above, so it'll wait for more sophisticated nested map management probably.

[curstwist]

looking great so far!

Do you intend to set fixed tiles for stairs? To prevent things like stairs spawning adjacent to toilets?

I think you're a bit confused about how stairs work, but yes that's one of the bugs this addresses
