[MERGED PR] ATMOS Pipe Repair and Replacement

[Studenterhue]

Pretty solid. Surprised there isn't much more buzz about this idea. It's not exactly completely constructable atmos systems like on other codebases but adding multiple pipe destruction states and making complete removal less likely does do a reasonable job of ameliorating how if you completely lose a pipe, you can't build another one due to the lack of constructable atmos (barring some obscure techniques). And hey, there might be better ideas, but this is a pretty good one.
