This makes it identical to it's real-life counterpart, and brings some actual sprite improvements upstream from Virgo.
Earlyport of https://github.com/VOREStation/VOREStation/pull/8812 with an actual rename of the gas, ID, and sprite used.
- var/uid was used in only a handful of places. Because areas are singletons
it is safe to replace the uid with \ref, areas don't get deleted.
- And with that /area/New() is empty, we can remove it!
- Set initialized = FALSE on unsimulated turfs that need to intialize.
- Most of area/New() to initialize
- Faster lookup of self-init on atoms
- Split air alarm and fire alarm files, move new to initialize
- Tweak decals and opacity
