Combination of #6743 and #6479, because I am a pro mlg git user, who
would never have issues with the master branch no sir
Doing surgery with another person watching, even if they don't wear a
mask, doesn't warrant an infection either, but beyond that you are
pushing your luck
However, doing surgery in this scenario:

Resulted in acute infections to the heart and lungs.
So, recap:
-Wash your hands, wash your tools if needed, clean your room, wear a
mask and nothing bad happens.
You can even invite a friend to watch over
-Do brain surgery in a blood filled room with 11 clowns honking and
breathing cooties down your patient, and it's just bad
//-Letting your patient go without closing the incisions is also bad why
would you even do that (NOT WORKING ATM)
Allows to use a droppers, bottle, drinking glasses, drinking bottles.
beakers, sprays, or if you are brave
enough, an entire bucket, to treat internal organ infections with
alcohol. The more alcoholic the thing is the more it disinfects. This is
an available option during organ manipulation, at the time where you can
apply trauma kits and etc, so you can for instance apply a trauma kit
and then drip a bottle of vodka over someone's liver to treat infection.
Also adds a debridement surgery to revive dead EXTERNAL organs. Same
list of utensils as the previous, lets you apply mithocolide on a dead
limb or chest to make it unded. Surgery steps are incision, scalpel,
applying a reagent container, cauterize.

Fixes:
- Spiders can no longer get stuck in vents, because they coccooned a mob
on top of a pipe, and it broke the pipe. Similarly, spiders can no
longer coccoon anchored objects of any kind. Fixes bug #6221 properly.
- Spiders will no longer ignore mechs and space pods. This was leading
to people cheesing the away mission with a ripley and a mech-mounted
drill.
- Prince, Queen, etc in away missions no longer stand still like
statues. Grays still stay on their vents.
- White spider in away mission can no longer infect people in a way that
makes it possible to transfer spiderlings to the main station.
- White spider eggs no exist for two minutes longer than they should
after hatching from someone.
- Signs in the away mission no longer contain the text 'improper'.
- Spiderlings that hatch in the away mission with an opened queen lair
no longer get stuck.
- Two misplaced lights in the away mission have been fixed.
- Queen nests in the away mission which live for a very long time can no
longer depressurize their area by smashing walls.
Updates:
- Webs spun by white spiders will infect humans who are silly enough to
walk into them. Hardsuits protect against this.
- Spiders will now be quicker to open doors. This should stop them
getting hung up on doors they can open.
- Empress has been tweaked to have an 'erase brood' ability (wipes
infestation, for adminbus), and her spit does BURN instead of TOX.
When a new Vox spawns in, your tail won't suddenly break (become a
different colour).
Abstracts icobase/deform/tail from the species definitions a bit so
individual mobs can have a different icobase/deform/tail than other mobs
of the same species.
- Updated the flashlight eye-shine check with the new get_dark_view()
helper proc
- Removed a useless check on the handle_dna() for monkeys
- Increases reliability of the monkeyize() proc and fixes issues where
calling it wouldn't turn a mob into a monkey on the spot.
- Increases readability/maintainability of the get_colourmatrix() and
get_dark_view() procs.
