Makes water coolers more mechanically interesting, fills them up with fruit punch sometimes (#92480)

## About The Pull Request

This overhauls Water Coolers (now referred to as "liquid coolers"
internally and in most external cases). They'll feel less like a useless
prop now.

(sprites may look off because of the gif software I use)

**Important Thing # 1:** The reagents are now handled by cooler jugs.
You can pop the jug off of a cooler, fill it with whatever the hell you
want, and put it back on. Fill it with drugs. Fill it with acid. I don't
care, I'm not your mom.

The sprite now uses an overlay to change colors based on the mix. Water,
when present in the cooler, is magically turned blue to keep that
classic water cooler look.

The jugs are 200 reagents, and are mechanically comparable to the jerry
can. No 200 unit acid splashes or anything.

Y'know, unless you put the jug in a cooler and knock it over...

**Important Thing # 2:** They can be anchored, tipped, and crafted.

Tipping them requires the cooler be unanchored. If you want to use one
of these tactically, unwrench it beforehand.

**Important Thing # 3:** They can be bought from cargo now!

**Important Thing # 4**

Fruit punch.

Fruit punch is a drink with impressive (slightly faster than omnizine)
healing qualities. Unfortunately, it's so unbearably sweet that it can
only be safely consumed near a liquid cooler! Drinking this stuff is a
commitment, since if you stray from the cooler while digesting it, you
will be hurt and disoriented. You should avoid drinking too much at
once, in case an emergency comes up!

For this reason, we encourage drinkers to _take small sips from your
paper cooler cup, hang around the cooler, and maybe chat with other
people who are healing too._

(Mapload) water coolers have a 1% chance to start full of punch instead
of water. Maybe you'll get lucky and start with a healing station in
your department, or maybe a hopeless space explorer will find one in a
ruin and be saved.

You can also buy one from cargo but it's priceyyyyy. It's also the only
source of punch.
## Why It's Good For The Game

Realizing how little functionality water coolers have was super
disappointing. They do hardly anything but take up space and look
pretty. And now, they're getting mapped into all of the new stations! We
can't have a bunch of inert, sandbox-shunning furniture just sitting
around, the other codebases would laugh at us!

Now, coolers are more congruent with how most people would expect one to
behave in the game environment. Even minor changes like making them
unanchorable or refillable helps them fit in with most players'
intuitive understanding of how atoms typically behave.

The reagent storage change gives coolers their own unique niche in the
sandbox. Tipping them over can also give you an edge in escaping
someone, so even the untouched roundstart coolers can serve a purpose to
savvy players.

For the punch cooler, I figured "why not make a reagent that rewards
players for treating the water cooler like a water cooler?" The punch
encourages players to stand around it, slowly sip from the cooler, and
chat with their co-workers. Just like people do in offices! It's
thematically sound!
## Changelog
🆑 Rhials
add: You may now remove water cooler jugs and put whatever you want in
them. Go nuts.
add: Water coolers are now craftable (with plastic), orderable from
cargo, and tippable when unanchored.
add: Rarely, water coolers will spawn full of healing fruit punch
instead of water! Be careful not to stray from the cooler while
digesting this stuff.
add: You can also just buy the punch cooler from cargo if you feel like
it.
