You can even make it rain ants, plasma, or drugs. All of their effects
get applied to turfs, objects, and mobs depending on the weather options
you select.

Did I mention... there is thunder?

Despite all this new stuff, none of it has been directly added to the
game but the code can be used in the future for:
- Wizard event - Similar to lava on floor, but this time make the
reagent random or picked from a list and give wizard immunity
- Chaplain ability - Maybe make this a benefit or ability once enough
favor has been obtained
- Admin events - I have added a BUNCH of admin tooling to run customized
weather events that let you control a lot of options
- New station maps/biomes for downstreams (Jungle Station, etc.)
- Change Ion storms to use the new weather system that triggers
EMP/thunder effects across the station
- IceBox could get plasma rain
- Lavaland could get thunder effects applied to ash storms

Relevant PRs that removed/added some of the weather stuff I used:
- #60303
- #25222

- Rain sprites were added via [novaepee](https://github.com/novaepee) in
https://github.com/tgstation/TerraGov-Marine-Corps/pull/9675
- Sand sprites were added via [TiviPlus](https://github.com/TiviPlus)
(who commissioned them from bimmer) in
https://github.com/tgstation/TerraGov-Marine-Corps/pull/4645
- Rain sounds [already existed on
tg](https://github.com/tgstation/tgstation/pull/25222#discussion_r106794579)
and were provided by provided by Cuboos, using Royalty Free sounds,
presumed under default tg sound license - Creative Commons 3.0 BY-SA
- Siren sound is from siren.wav by IFartInUrGeneralDirection --
[Freesound](https://freesound.org/s/46092/) -- License: Attribution 4.0

The original `siren.ogg` sound used on a lot of SS13 servers doesn't
seem to have any attribution that I could locate. The sound was added
about 15 years ago. So I just looked for a somewhat similar sounding
siren noise on Freesound.

More weather customization!

🆑
add: Added new weather types for rain and sandstorms. Rain now uses a
reagent that gets exposed to the turfs, mobs, and objects. There is also
a thunder strike setting you can apply to any weather.
add: Hydro trays and soil will now add reagents to their trays when
exposed to a chemical reaction. (weather, shower, chem spills, foam
grenades, etc.)
add: Weather temperature now affects weather reagents and mobs body
temperature.
bal: Snowstorm temperature calculations were tweaked to allow universal
weather temperature effects.
sound: Added weather sounds from TGMC for rain and sirens (attributed to
Cuboos and IFartInUrGeneralDirection )
image: Added weather images from TGMC for rain and sand storms
(attributed to Novaepee and Bimmer)
refactor: Refactored a lot of the weather code to be more robust
admin: Admins can now control more weather related options when running
weather events. The weather admin verbs have been moved to their own
"Weather" category under the Admin tab.
