Different parts of the brain can now cause different kinds of brain damage

[content]

What this does

currently the only way this can be achieved is surgery. impedrezene and every other thing that caused brain damage already still affects everything it used to.

adds an option during the surgery step for using a scalpel on an exposed brain, to damage a certain part of it or to sever it as normal.

the parts (which all show up on body scanners if damaged) are:

Cerebellum: affects motor issues (legs failing and causing you to collapse, hands making you drop things)
Frontal lobe: spacial judgement, the thing that makes you headbutt airlocks
Broca's area: speech, makes you speak gibberish
Temporal lobe: affects intelligence, making you too dumb or "undextrous" to use machines
Occipital lobe: makes it hard to see occasionally and briefly

your head hurting is the only thing left that any kind of brain damage affects.

currently any damages to these can only be cured by patching the brain up with gauze in surgery, mednanos or peridaxon; as this is currently the only way a broken or bruised brain can have its damage healed (yes, alkysine does not affect this) but i can make alky and etc cure it if it's really requested since i added some commented out code that supports this.

Closes #34022.

Why it's good

lets surgeons brain damage people in very specific ways, for example if they just want them to say dumb stuff but not headbutt airlocks.

How it was tested

doing the surgery on a spawned human. putting them in a body scanner, applying gauze to their brain again to fix it. brains can still be removed as normal too. setting brainloss to 70 on the player, using alkysine to remove it, setting the specific kind of brain damage for speech on the player, admin rejuv-ing to remove it.

Changelog

:cl:

rscadd: Surgeons can now use their scalpel to damage specific parts of patients brains to affect performance in them. This includes areas that affect limb usage, headbutting airlocks, speaking gibberish, and being able to use machinery. All other forms of things that caused brain damage still affect all four as normal.
