Changes to ventcrawling.
Created by: ComicIronic
Feature freeze hasn't started yet! Ventcrawling now actually puts you in the pipes and lets you move around. You get an overlay of all the pipes in the network you're currently navigating. Altclicking on a vent now specifically lets you crawl into that vent if there are other vents in the area. You can now ventcrawl into scrubbers as well, because there's no real reason not to. Scrubbers are weldable to compensate.
