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.
I actually forgot to do this before the event system went permanently live so that's on me.
Anyways this turns off swarmer drones from being able to be picked by the GM system, since right now they're, to put it charitably, poorly balanced and implemented (being super-maint drones is very clunky to me but thats not the main thing).
When the GM system spawns one in, it tends to result in a ghost becoming the drone, then that player essentially never being able to lose due to infinite re-tries and the crew has to fight off drones for the rest of the round or until they or the drone gets bored.
There's been quite a few number of rounds that have devolved due to them so for now it's probably best to turn them off for the time being.
Fancy that a downstream noticed this and got me to check all the way up here. So fix here, too for all the rest down the line.
Changelog Notes:
- Fixes typo in Solar Storm announcement with refrain being spelled "refain" instead.
- Best practice to avoid holding onto references to the subsystem instances aside from the global variables. (In case of restart/recover etc).
- The reference to GM was entirely unused by any event or meta-event. /datum/game_master would work fine using the global refs.
