Adds door seals to the game, inspired by the ones used in Alien Isolation and SOMA. Trivially easy for a human to remove, but makes it a nightmare to try and smash through if you're an alien, an evil robot, or don't have hands. I also slightly changed how airlock reinforcement works, as now there are two ways to increase the integrity, the previous way of just resetting the max_integrity after the removal of the plating wouldn't work.
