Title: [WIP] [MAP] Makes walls into /obj/structure/wall

Exactly what the name says. Also repathed all walls in all the maps.
This is a WIP for two reasons
* Fires are breaking (they won't spread to neighboring flooring for a while and them everything will catch on fire. also they can carry heat through walls)
* I probably broke a ton of stuff during the repathing and haven't found them yet
