## About The Pull Request
[A common problem with explosions is an overabundance of
sleeping](6499077a09)
In an attempt to solve this issue, let's not continue to sleep and do
work in door closing if the door is already deleted
(This is caused by firelocks activating due to other adjacent objects
deleting, triggering an atmos update, and closing the firelocks before
they get bombed. I don't have a elegant way of resolving that core
problem, so let's just minimize the impact)
[Nukes a stupid sleep loop in airlock
code](5b16360520)
When an airlock was depowered, it would enter a sleep loop, decrementing
its delay by 1 second every well, one second, so long as it had the
right wires flipped
This is very stupid
Instead, let's use signals off wire changes and a combo of timer and
remaining time var to do this with JUST a timer
Most of the changes here are just swapping over wires to a setter to
make signal registration work\
## Why It's Good For The Game
Less sleeping around explosions means less dropped ticks after a bomb
goes off. Good just in general
Also this excises dumb boomer code and adds some hooks for other devs to
use (we should use wires more man)
